exsilky,
For a proper ID (if possible), photos will be needed.Include photos of of all marks,including the proofmarks under the barrels.The following is a "stab"at it using the info you provided.It seems the seller was C Krummel from Eberswalde.The barrels were madw of "Prima" Krupp,fluid steel.It seems to be chambered for 16ga in the shotgun barrels.The 16/1 is the dia. of the bore ahead of the shotgun chambers.The 118/35 is the bore(not groove or bullet)diameter expressed in ga.This mark can be found on rifles chambered for one of several 9.3mm cartridges and some 9mm. One of the most common would be 9,3x72R. The proof load was 29grams blackpowder and 27 grains lead.All this is subject to correction or revision, depending upon new info/photos.Additionally,the gun was likely proofed between 1893 and 1911. I hope this helps.
Mike
