Thanks Ed. I took a macro of the inside holster marks;
Actually, now that I look at it in macro, the letters might just be a big "N" and a small "o" for Number?
The flash completely wipes it out but to the naked eye it is a lot darker.
There is also some fine lettering stamped into the back of the holster that I have not been able photograph. I'm going to have to take it down to my friends studio to get any sort of usable image.
It's;
OST JAHNEL
ESLAU
With maybe 1940 stamped below it? The "date" is considerably lighter stamped then the other letters and is not set with the letters above. Which to me says it was not stamped at the same time or maybe somewhere down the manufacturing line??
The back of the holster also has my Grandfathers last name scratched into it with some other information I'm assuming is how he identified it and got it home. We had some similar processes when I was in the military but I never got to take any weapons home
