Can you tell me what the initials are on the underside of the left scattergun tube at the end of the "Krupp Fluss Stahl" stamp, or maybe a "Crown" over "S"? Looks like a set of initials right under the "8.7mm" stamp on the rifled tube just about the Gothic "J" which I think noted the Jaeger craftsman. The rifled tube may have experienced the preliminary proof more than once as the "Crown" over "G" is either pretty low or beside a worn "Eagle". The tube may have been modified to accept the normalized 9.3X72R or maybe it was proofed separate prior to 1912 and then again under the 1912 rules. The Drillinge is a No. 8 and described as follows:
"8. Hammerguns with three barrels, Roux action, double bars and forwarded rib, best rebounding locks, insertion for ball by lever on the disk, visor to lay, on simple stock, plaine line engraving."
The marks date from 1912-1923 but if I'm not mistaken, I think the 9.3X72R was normalized circa 1914. So it would have been made between 1914 & 1923. Many times an example finished in F.W. Kessler's shop will have the FWK monogram on the standing breech.
Kind Regards,
