Yesterday, I received a note from the GriffinHowe research guy and at this point he can't find the production date on the Francotte.
For years looked for an upland ten bore, finally found a Francotte BL Ten Damascus at 7# 12oz. Beautiful condition. Have questions. Can't find the serial number in the Production table, SN is 18572. stamped on the right barrel,trigger guard and the watertable. Not on the forearm iron. Oddly on the left barrel a #19880 is also stamped. Also, the chokes are Right .742(Full) and left at .762(Light Mod). Backwards??? Francotte Chokebores on barrel flat. Not For Ball on both barrels. Bores are bright, so an agressive hand on the left bore might be the culprit on the LM choke or original. There is a very small LD 2 on the watertable and #2 on the forearm iron. Part of a 2 gun set??, "A. Francotte Maker and Patentee London" on the side of the frame. "Anson and Deeleys 3376 Patent" stamped on the standing breech wall. "Von Lengerke & Detmold New York US Agents" on top rib with gold bar preceeding. Beautiful sculpted pattern on the rib. Fine scroll engraving throughout, original case, faded but obvious, clear and distinct damascus pattern.
Second gun. Anyone with the data for a DOM for Wm. Cashmore, Birmingham, BL. SN#20600???
Thanks for your help. Randy
