Nice score for a flea market!

Wow, nice find for sure! Congrats 

Today's flea market find a Kriegsmarine NCO parade jacket

No markings anywhere.  The pistol is totally devoid of any marking other than the year 1939, the "S/42", and the two parts that just have "42" stamped.  I had wondered would there have been a use for 'clandestine' pistols with no traceable serial number.  But why have a maker mark?   I also suppose it could have been battle damaged where the serial number was and maybe replaced with factory coded replacement parts.  But again, there are no WaffenAmt marks anywhere.  It is a very strange pistol.   Or is it the obvious that it is low serial number '42' which is sheer coincidence that would be the same Mauser '42' code?   Or the assembler at the factory was 'asleep at the wheel' and did not mark it...   Or is this a Germn equivalent of a 'lunchbox' pistol illegally taken home as parts from the factory and smuggled out...   I am stumped on this one...

Nice display! I really like GI custom grips.

Sarge, I think you´re 100% correct. It´s a "s", not a "5",  and s./l. (seinem lieben) makes absolute sense.

Don't think I posted before? This is a pistol I picked up about 9-ish years ago. No finish, theater made grips and it was frozen with the slide in the locked back position. Kinda sickly looking but for $185, why not.  Found out the recoil spring collar was assembled incorrectly at the muzzle end, jammed tight and the recoil spring itself was in pieces. Got it apart, reassembled correctly and now it functions. I've run about 2-3 magazines worth of ammo thru it. It resides most of the time in this shadow box with other period nicknacks. Found an original WW2 patch for the 152nd Engineers so it kinda fits the theme!

“It is only marked with maker code of S/42 (Mauser) and the year 1939.  Any other markings on parts are just '42' There is no serial number anywhere.  No Waffenamt stamps anywhere”

Look closely at the markings and see if you can see either a WaA or Nitro commercial stamp.  The WaA will be an eagle over "WaA / letter or number" while the commercial marking of an "eagle / N".  There may also be a Police marking of an "Eagle / letter" under the wing.   What is the full serial number (including the lower case letter) to see where it falls in production.    

Thank you very much for this information!  I sincerely appreciate it.

There are several types of family crests similar to this one.   It is difficult to distinguish between them completely.   ●Mitsu-uroko【三つ鱗】 https://irohakamon.com/kamon/uroko/mitsuuroko.html   ●Tanegashima-uroko【種子島鱗】 https://irohakamon.com/kamon/uroko/tanegashimauroko.html
