Yep, same Crown over M adjacent. I have wondered what that stamp might have been. Excellent effort. Still with the 24x4xxx your manufacture date is going to be circa 1911/1912. Looks like same 726 number also. Not sure on the U but the D notes that components were sourced from a D mechanic.

I'm going to say the Nr. is 246486 being DRGM 246486 or Gebrauchsmuster Nr. 246486.

I have read where the U stands for inspection, I wonder if that would apply for the D U area.

There are U marks with a crown adjacent on other parts as were show in previous pic's.

1911/1912 she's a little over 100 years old, interesting.

I am going to take a small brush and very lightly brush the drgm area to see if I get a better pic of those numbers, I am worried about doing damage so it will be very lightly for sure.

Indeed a Crown over U represents inspection after a proof effort but this U, if that is what it is, is not a proofhouse touchmark but rather a component maker's mark like say Ulrich and there is another or two family of mechanics whose last name begin with a U.

Apply chalk or soap after your touch-up effort.

Forgot to note that the D near the forend hanger more than represents sourcing of components & it may represent effort also. A guess would be Heinrich Diem of Benshausen bei Suhl. Denecke & Co. as well as Gebr�der Decker but both were in Zella-Mehlis and I doubt cross-sourcing to Z-M, but it is possible. D is a common stamp in that position & on the forward part of the right flat on Suhl sourced sporting weapons. I do not believe I've ever seen the stamp of a D on a Sauer manufactured sporting weapon.

In January 1908 the following protection period for the following DRGMs was extended:

241475
242003
243380
252826

In July 1908 Carl Stiegele of M�nchen paid the extra 60 marks and extended the protection
period for DRGM 247832

So the DRGM stamped on the tubeset had to be applied for in 1905.

Big Redneck,
WD40 and 0000steel wool is mild enough that you won't hurt it.Electronic calipers are cheap enough now(other than top of the line)that everyone should have 3(1 for the shop,1 for the loading room,and 1 for the den).They are easier than dial calipers,certainly easier than vernier calipers.Also, I use mine to convert in/mm and mm/in.Then you wouldn't need a machinist to measure for you,just remember to "zero" the scale.

Here in Northwestern Pennsylvania we have about a foot of snow on the ground. It warmed up and rained last night and it was 34 degrees at 7:30 A.M. this morning, it is now 1 P.M. and the temp is 18 degrees. Solid ice everywhere.

I will get a better set of calipers and hope to find material to do the casting at the local gun shop when I get out and about.

I will try the 0000 and WD40 this afternoon.

I Did some clean up and took some more photos


I think the number is 2404XX



found this mark on the shotgun barrels
