Proof mark?
 

What is this Proof
Thank You

The Eagle 6 is a Simson proof. I don't know what might be stamped to either side of the 6?

Thank you Jerry , any idea what time period it was used?
Thanks

Simson was dating pistols in 1926. It's the only date they used I think? Somewhere in that time frame.

Ed Tinker is the Simson expert..he might know what the whole thing is.

Please post more pictures of your pistol and all markings.
Looking at one mark out of context can be misleading.

That is an Eagle/33, one of the Simson inspector markings; though it does look like a
"6" slipped in between the "threes" somehow.

It is an inspection or acceptance marking not a "proof".

Simson made parts and pistols and repaired pistols(lugers) throughout the 1920s and into the 1930s; New production was dated only in 1925 and 1926(few in '25 and even fewer in '26).
Most Simson production was not dated on the chamber at all.

Many Simson made barrels were sold to and used by the police in rebarreling their pistols, the barrels themselves will have the last digit of the date on the bottom;
a 3,4,5, perhaps a for the corresponding year 1923-6. Maybe a couple others but all the barrels seem to have been made or marked at least in the early '20s.

Would be interesting if you could post some more close-ups of your Simson.
Simson Lugers are not seen that often.

Posted this one on another forum , thought I would share here for a little more info on assembly (where and when, etc) included more photos. It’s marked very similar to a 1940 byf pg. 261 The Mauser Parabellum 1930-1946
Thanks for your time

Your second Luger is rebuilt with parts from a number of different Lugers and arsenal rebuild replacement parts.

The "byf" prefix didn't start being used until 1941 (the Mauser concealment code was "42" until 1941 - so all 1940 made Mauser Lugers will have "42" on the toggle).

The side plate is an arsenal replacement part shipped from Mauser as a spare part.

The "byf" toggle is marked in a non-standard way. It's original serial number marking at the rear was removed.

I don't recognize the form of the eagle stamps on the barrel. I'm not sure that the replacement barrel was done by an arsenal or field replacement workshop.

Same Luger with the Simson mark on the barrel, eagle markings on barrel appear to be eagle n as well as the one on the frame and toggle

The barrel was originally made by Simson- likely in 1923 from the "3" seen on the barrel.
It was added to the 1940 luger by a third party and proofed as a "repaired" pistol as indicated by the
added 9mm, E/N, and E/J .

The E/N is a proof mark, and the E/J indicates repaired (in this case likely the barrel replacement and perhaps other small parts).

Repair is also noted by the non-standard numbering on the replacement(42 code) side plate, and rear toggle. The HZa marked extractor is also a replacement.

Note, the e/N and e/J stamps are civilian, not military.

Any ideas of who may have assembled it?

Yes e/n commercial proofs

The E/N & E/J are IAW the 1939 proof laws and, as noted, are civilian/commercial proofs.

The picture below shows the barrel proofs on a pistol rebuilt by Frankenschloss during the same time frame.

Thank you for the link. While it has a lot of good information, some of it isn't accurate. For instance, the Eagle/N proof is said to be a Mauser commercial proof mark. It's not exclusively Mauser but a commercial proof used on guns from all manufacturers where appropriate.

At least it a start. Ralph sent me his red and gold cover. 'Proof Marks" Its too big!

I have the same Costanza book. It's autographed. It's surely a chore to wade through all the listed proof marks to find a particular one. When I used it as a reference once, I was told it was outdated and in error. Even so, it's still a useful reference. :)

It has a pretty cover but I agree! 430 pages I went cross eyed!

E33 - but it does look double stamped or the like
