Certainly the "M" in "MAC" is not an M but an upside-down W. Also, it looks like the W and the Z in the second photo were superimposed on other stampings. Don't know what you mean "standard and in good bud", since the front of the crankcase is missing. Could it be a demonstration tool and that's why the numbers don't make sense?

That was a strange experience, 80052 is the frame number of my 1942 bike. I have been looking for the matching engine for years. It does however seems to have been re-stamped but still.

I would buy engine WM20 80052 in any condition but preferably still in serviceable condition of course.

Isn't the 'inverted stacked rifles' an international distress sign ?

I've seen a few Norton engines open at the front like that but usually with half a con rod and a bent camshaft hanging out.
