Fuhrmann have send me a link about a remarkable rifle. its our opinion that this started as a muzzle loader percussion Jägerbüchse. much earlier as 1880, I believe around 1860.
this muzzler loader was sometimes build into a breech loader for a now unknown 13 mm cartridge. maybe it was the 12,7x60R or 65R 500 BPE. if the gunmaker M. Band from Suhl was the maker of the muzzle loader or did the overhaul?
some years ago the rifle come on the workbench again, now got a liner for the 5,6x50 R and a scope with a claw mount. for me a pointless work but thats the history of the rifle.
