Today I viewed at least a baker's dozen of drillings at the Alabama Gun Collector's show in Birmingham and one was an underlever proofed in Zella-Mehlis during 3.12(March 1912 - Suhl began with the new proof rules in April while Zella-Mehlis led the way beginning on September 1st, 1911) that had an older Krupp stamp on the top of the scattergun tubes but also with a "Acier Cockerill LLH" stamp on the bottom of the scattergun tubes but with a Krupp rifled tube. The guy reiterated that it had Krupp tubes because of the Krupp stamp atop and I told him that it didn't matter what was stamped on the top, the scattergun tubes were Cockerill steel sourced from LLH. Interesting mixture and I'm suprised the Cockerill was filed off if the owner wanted Krupp tube steel. I am beginning to be suspect of any steel type tube stamp unless supported with an analysis.

Kind Regards,
