I think I may have located fragments of the crossed cannons. About an inch or so from the oiler cutout, about level with the bottom of the cutout. Is that correct placement for the crossed cannons?
That was my mistake on the punch mark thing. I saw it on the bolt too, so I assumed...
I'm working on the markings and types for all the parts now actually.
Inland Type III bolt
IBM Type II slide
Magazine catch appears to be marked "WA" just above the "M"
Rear sight has an "H" inside of a shield
Front sight has the "Z" or "N"
The hammer is marked "HI"
Trigger guard is Winchester I think. Though it has a "C" and a "U" stamped into it, so I'm not sure
What exactly do you mean by that?
