punch marks on 1939 s/42
 

I am interested to know about diamond punch marks on my luger. On the right side of the receiver around the takedown lever end are 7 diamond punch marks at 3 to 6 oclock positions. also on the face of the takedown lever itself on the far left edge are 2 diamond punch marks. At first I thought they may be a way to tighten the lever fit but why on the face of the lever. I have searched thru your threads and have found no reference. the punch marks are very tiny < 1/16 tall. Any ideas?
TIA

A couple of photos would help Al... but from your description, my best guess is that someone at some time in the past had your Luger in a vise :eek: and the diamond pattern was on the jaws of the vice... but show us a couple of photos and it will be easier to determine.

Speaking of punch marks. I notice that most WW2 military lugers I handle have single, round punch marks on them in various places, usually near the toggle joints but not exclusive to this area.
Does anybody have an explanation for these single marks, that are clearly deliberate and not a handling ding?

Alanint, these marks are usually hardness test marks done at the factory during test firing to make certain the metal meets the minimum hardness standards.

I thought of vise marks but these are not in a pattern, more random spacing and not lining up in rows like crosshatching . If I can get the camera to take decent closeups I will post pics

My camera wont take close enough pics to see the marks. I tried using my kodak program to zoom in wich I can do but it wont let me save the zoom pics. Fustrating as all get out but i'll keep trying
