Willie Macrae Part 16: Gun – Physical Aspects


Parts 12 and 13 looked at the evidence, released by the authorities, about where the gun was found and how it got there. 

In Part 14 we saw how the Crown office contradicted itself over the number of bullets recovered from Macrae during his post mortem.

Today in Parts 15 and 16 we look at what else the released documents have to say about the gun itself, the bullets and spent cartridges.

Part 15 dealt with one key point in particular but also raised other points of interest (to me at least).
Here Part 16 will deal with physical aspects of the gun, the post being split into four sections,
- what gun is it?
- how this gun works
- the gun worked but ….
- implications for Macrae case

What Gun Is It?
macrae 2

In their 1990 book published 15 years before Northern Constabulary released photographs of the gun and details of the  firearms testing, Scott and Macleay claimed that the revolver was from 1948 or earlier. [Tartan Terrorism and the Anglo-American State ’ by Andrew Murray Scott and Iain MacLeay, Mainstream Publishing (1990); the relevant chapter is available here],

They were correct that it was earlier than 1948 but were much further out than they could ever have imagined.

The gun was at least 117 years old when it was used to kill Willie Macrae.

I am utterly confident that the revolver found was a Smith & Wesson Model 1 2nd issue produced no later than 1868 [between 1860 and 1868].

I’ll explain soon why I am so confident but I am not alone.  In early January this year, and totally independently, Robert Lewis blogged about Macrae and came to a very similar conclusion.  He wrote,
The pistol MacRae is alleged to have owned, and shot himself with, turns out to be a Smith and Wesson Model 1, of the first or second run. That means it was at least 117 years old.
I believe we can rule out the 1st issue of the Model 1.

What Led Me to this Model?
Strathclyde Police’s firearms report was critical.  They described the gun as,
A 7 chamber, top hinged, external hammer, single action revolver of American manufacture (Smith & Wesson) designed to chamber .22 short rim fire cartridges. It bore the serial number 90686 and was in fair outward condition.
A Google search for
Smith and Wesson 7 chamber .22 top hinged single action
gave me the Wikipedia’s page on the Model 1 as the top hit.  When I saw photos I knew I had found the gun.  Had I searched with ‘Smith & Wesson’ I would have taken longer to get home.
The next image – of an Model 1 2nd issue - was on that page and below that pic 6, from above, tweaked to show just the revolver.

Other than the engraving and the handle in the Macrae gun they look identical.

On the next two images I have highlighted 7 small features which are identical.

Don’t be put off by the engraving on the Macrae gun.  Smith & Wesson made specials.  For every two hundred or so standard Model 1 revolvers, one or two were factory original full silver plated finish and/or ivory grips. 

Beyond this too were some which were factory engraved.  Many photos of such are around, for example,
SmithWessonModel12ndIssueA
this gun which is engraved and has a pearl handle.
Welsh described the Macrae gun as
His partner Welsh was aware that Macrae possessed a small calibre, possibly .22 revolver, which was chrome, silver finish with a pearl handle. [Macrae A syn]
Unfortunately, the Macrae photo quality is so poor that we cannot tell if the handle is light wood, ivory or pearl.

But handle apart I hope you’ll agree that the Macrae gun is matches those displayed here.

The Model 1 was manufactured between 1857 and 1882, there being three variants - 1st, 2nd and 3rd issues.

The 1st issue can be ruled out for two reasons.  Firstly the hammer, in the 1st issue, was of two part construction whereas the 2nd issue was a one-piece hammer

Part 16 SWModel1I1 Hammer
Part 16 SW M1 I2 Hammer







                1st issue                                                                           2nd issue

and secondly on the basis of serial number. 

Only about 12,000 1st issues were made (between 1857 and 1860, serial numbers 1 to abt 12,000) and the 2nd issue serial numbers followed on from those used for the 1st issue (between 1860 and 1868, about 12,000 to about 120,000).

The Macrae gun’s serial number, 90686, falls outwith the 1st issue and towards the top of the 2nd issue production.

But the serial numbers for the 3rd issue were reset and they ran from 1 to about 131,000. The Macrae gun’s number would fit within this range too.

Fortunately the 3rd issue incorporated a  design change which rules this out as an option.  The grip design was more curved as shown below.

Part 16 SW M1 I3 Grip
Part 16 SW M1 I2 Grip
              2nd issue                                                                            3rd issue

Therefore, I am convinced that the gun which killed Willie Macrae was a Smith & Wesson Model 1 2nd Issue 7 shot, top hinged, external hammer, single action revolver designed to fire 0.22 rim fire cartridges made between 1860 and 1868. 

These guns were not the first but were early adopters of self-contained cartridges i.e. where all the components necessary to fire the projectile were contained within one package.

How This Gun Works
The Macrae gun is a single action revolver which, possibly counter-intuitively, requires two actions to fire whereas a dual action revolver requires only one action to fire!

The two actions for the Smith & Wesson Model 1 are ,
- pull back the hammer which rotates the cylinder and puts the next bullet to be fired in the correct position (i.e lined up with the barrel
- squeeze the trigger which releases the hammer which initiates the series of actions which result in the bullet being expelled from the cylinder and barrel

In this type of the gun the trigger has only one action, hence single action.

With a dual action gun, squeezing the trigger pulls the hammer back, rotates the cylinder into position and initiates the firing sequence.  Therefore, the trigger alone does the two actions listed above for Macrae’s gun.  Hence dual action.

Macrae’s gun uses .22 ammunition.  The ’.22’ refers to the maximum diameter of the cartridge in inches.  Therefore, Macrae’s gun uses cartridges which are .22 inch in diameter (i.e. 0.22 x 25.4mm = 5.6mm)

The gun worked but ….
That the gun worked is obvious unfortunately but one part was so worn that it didn’t function correctly.

I mentioned in the previous section that pulling back on the hammer should rotate the cylinder and put the next bullet in line with the barrel but that did not work in Macrae’s gun.

Part 16 Macrae R E2 Mod 1
Therefore, the killing gun required three actions to fire:
- pull back hammer
- rotate the cylinder
- pull trigger
Now this extra step is clearly no show-stopper.  Whoever pulled the trigger went through this process.  The gun works.

But there might be another complication.  From the admittedly small amount of reading on revolvers I think there are two aspects of cylinder rotation to consider.  The first I have already described: the cylinder did not move on its own and so had to be manually placed in position.  The second is that there is a mechanical stop which maintains the cylinder in the correct position.  I don’t know if this was part of the Smith & Wesson Model 1 2nd issue and, if it was, I don’t know if it was working.

Why is this important?

Well, if it worked then once the cylinder was rotated into position it would be held there and the alignment of cartridge and barrel would be maintained.  If not present, or present and not working, would mean that there was no fool-proof way of aligning the cylinder correctly and no way of keeping it in that position until fired.

The diagrams below show the three possibilities proper alignment, large misalignment, and slight mis-alignment.

Part 16 Misaligned Cartridge
Part 16 Aligned Cartridge 1
Part 16 Partially Misaligned Cartridge

With proper alignment the orange cartridge is symmetrically aligned with the green barrel and the hammer’s pin (black spot) strikes the cartridge on the rim (hence rim fire cartridges) and detonation and firing occur properly.

When the cartridge and barrel are badly misaligned the  pin misses the rim of the cartridge and, clearly, no detonation can occur.

With partial misalignment the rim can be struck with the possibility of detonation and firing.  What happens then, I don’t know.


Implications for the Macrae Case
There is nothing about the gun, its age, type, mechanism or flaws which favour suicide over murder or the reverse.  I’ve researched it out of interest rather than with any hope or expectation that I would uncover an important fact.

The gun killed Macrae.

There are many unanswered questions though:
- why did he have a gun?
- why such an old gun?
- why such a small and low-powered gun?
- where did he get it?
- when did he get it?
- where did he get the ammunition

  1. That the gun caused at least one bullet to enter the head seems to be all we need to know about the gun itself, as opposed to knowing who fired it, and when, and why.

  2. Ach, can you not let a man (an old man) wander where his interest takes him?

    1. Wander on old man, I merely summarise...

    2. And my overall summary so far:

      It was either suicide or murder and thus far I have seen no evidence of murder

    3. Nor would I have expected you to see any evidence of murder: there is none within the officially released documents.

      It isn't vital for the anti-suiciders to show direct evidence of murder. If they can, then that strengthens their position immeasurably but they need to find one substantiated point, at least, which breaks the official narrative. I'm not sure that they have one of these either. As you know lots of questions have been raised but none with the certainty which breaks the official line.

    4. I appreciate and understand your interest in every detail. My only interest is to hear any evidence suggesting it was not a suicide. I expect, as in many cases, both suicide and murder will have to remain as at least theoretical possibilities, but evidence suggesting serious consideration of a murder scenario is what would really grab my attention. It is not a criticism of your process to say I have not seen that, and I will continue to follow your analysis.

  3. Oh, I hadn't seen your comment as being critical. Apols if it came across in that way although, having re-read my first sentence, your interpretation is understandable.

    Let me try again to say what I had intended.

    Although still neutral, I've been thinking about what is required to get an FAI. There is a view amongst those who question aspects of the official narrative that there is sufficient evidence (or doubt) for an FAI to be held.

    There are undoubtedly a multitude of questions but I haven't seen anything sufficiently robust to either move the Scottish public or, more importantly, a Crown Office which is fixed on suicide.

    Evidence of murder would drive the process but, as I said, I haven't seen this. If not this, then anything which broke the narrative or showed an on-going cover-up would also be of benefit.

    Therefore, the challenge to the pro-FAI grouping is to produce something absolutely rock-solid which cannot easily be refuted.

    Will the challenge be met?

    ?

    1. I wrote in comment above, ' Apols if it came across in that way'.

      This would have read more clearly had I said,

    2. "your interpretation is understandable"

      Actually, you have misinterpreted my interpretation, as I did not interpret that you thought my comment was critical but was just making the point that it wasn't. So that's that all cleared up again :)

    3. I give up!!! :)

      Should know by now that you are nothing if not contrary. :)

    4. On the contrary, I am not contrary, I merely try to be precise, which often involves contradicting people's mistaken assumptions and presumptions, that are often made by trying to read deeper meanings into words instead of just reading the words. I await your next post with interest.

  4. Precision? Mistaken assumptions? Presumptions?

    I have just read your words. I have tried reading deeper meanings into your words. Still I am confused.

    I await your next comment in confusion and with trepidation.

  5. "I have tried reading deeper meanings into your words"

    That is the mistake. If I had meant something deeper I would have said it.

    ReplyDelete
  6. I add 3 words and then some more.

    'I have just read your words.' I am confused.
    'I have tried reading deeper meanings into your words. Still I am confused.'

    I have clarity now! Either you are contrary or you are confused.

    With this insight, I can approach your comments with lightness and not dread. Phew!

    1. I truly have not got a clue what you are going on about now, but that does not matter. I'll be looking out for your next instalment. Best wishes, Andrew (and the good news is that Starbucks here in Perth has not auto-blocked you even if the library has).
