New Guy Post: I need help identifying my 1935 Luger a bit more

[WestinHill]

Hello all,

First post here, so feel free to offer any comments/advice.

I could use some help to (hopefully) figure out what branch of the German military this pistol would've been supplied to after being manufactured. My research has told me that it could be a military issue or a police issue - which doesn't make sense to me.

I've been able to identify a good portion of the markings and symbols to provide me with at least half of this weapon's story:
All of the serial numbers match on all of the components.
Based on the markings on the top of the pistol, I know that it is an S/42 G series Luger produced by Mauser in 1935, after the K series was produced in 1934.
But I can't seem to narrow it down further from there. I am unable to find concrete info on all the other stamps located on the barrel and side of the frame.
I also can't seem to identify the "serial suffix" lowercase letter that is marked under the barrel above the trigger guard. It almost appears that it could be "b" or an "e" but it also looks like the marking could be damaged, I cant tell.
Any help or advice to identify this Luger would be greatly appreciated!

Cheers!
