I just traded into an old hammer drilling :12x12x ?.
The rifle barrel is about 45 cal and a 444 Marlin drops into the chamber. The maker is "D. Sauerbrey--ULM". The barrels are marked "Kruppscher Stahl". It's in reasonably good shape except for some pitting in the shotgun barrels. The rifle barrel looks unfired. The bluing is still excellent except for the area over the hinge pin. The lockwork is tight and the lockup is tight. It is an underlever with a steel trigger guard.
Any info would be appreciated. I know one of you guys knows what this is.

There's no rifle caliber designation stamped on it?? Usually on the underside of the barrels hidden by the forend? If not, you may need to make a chamber cast and measure it to see what size the rifle cartridge is!

Dr. Duc check with the people at www.drillinghotline.com they might know.

Does it have Belgian proofs stamped anywhere? Just wondering, I think a fair number of otherwise unmarked guns of this type (perhaps more so Cape guns) come from the 'generic' Belgian trade. That's my hunch based on a bit of reading, and browsing any I can find on the internet sale sites. H. Pieper comes to mind as one maker -- I've seen one of their shotguns, nice work. Can't say I've ever seen a drilling advertised as being made by them.

This gun is German Proofed in Suhl and Ulm with old marks and post 1950 black powder proof marks. The bore is over 11mm and as long as a 410 shell. I emailed Joe at Drilling hotline and he was polite. It is not fancy just a workman like gun that has seen use but not abuse. I can't find my cerrosafe or I would have laready measured it. It is very light for a 12 ga-6 1/2#. Interesting gun.

Dr. Duc If you can measure the rim thickness and the rim diameter, also the diameter at the back of the chamber. I realize you probably do not have a case, try and get the measurements off the bbl.

If you can post a description of all the proof marks and numbers we might be able to come up with something. Unfortunately it's almost always necessary to cast the chamber of these old guns to identify the rifle round.

And with any German made rifle the barrels need to be slugged to find the actual diameter of the bullet, also the length of the chambers of the shot barrels! You listed post "1950" black powder proof marks?????????? do you mean it was reproofed after 1950?

The proofmark info says "post 1950 Black powder Proof". I assume that is it was proofed after 1950 for loads equaling the old black powder power. I know it is dangerous to assume with European guns. I'm looking for some soft lead to slug the bore and the chamber base is.493 as best I can tell without a cast. This looks like it may be the 11.3x50R but I'll reserve judgement until I can get a cast.
The shotgun barrels are pitted but the rifle barrel is virtually new. Looks like the gun was used routinely as a shotgun but lack of rifle ammo stopped that.
On a humorous note, I took it to a friend who is a dealer with an interest in drillings, in the truest gundealer fashion the first words out of his mouth were 'Nice old gun. Looks like it's been reblued."
All in all this is turning into a project.
