I have picked up a 1874 Sharps "repo?" in a trade. Half round, Half oct. bbl. stamped on the flat is Sharps Rifle Co., Dayton, Ohio. This is also faintly stamped on left side of receiver. Also on bbl. is "Old Reliable" logo. it is marked calibere 45-70 govt. It is a nice rifle, with really high grade wood, 28" bbl, case hardened receiver. I can find no other markings with exception on sn, stamped just ahead of tang on receiver, the extractor, and the barrel. Does anyone have any infor on the mfg of this rifle?? All info appreciated.
