I just bought a backlock rifle. I was told,and a card that came with it, is it was made in the 1850s by J.D. Winchell. Mr Winchell was a road commissioner in Hillsdale County Michigan in 1860s. Barrel is 30in muzzle to breach plug first 10in is octagon to round, only stamp underneath is Remington steel. gun is 45cal. It has brass butt plate and trigger guard ,pin and nose cap are pewter. backlock has no markings I could see. It has set trigger, have to set rear to cock( no half cock) .stock is probably refinished but barrel patina seems original. Judging by research I think it is a northern Kentucky/southern Ohio build half stock .any information on style or maker is appreciated. Thanks,
Bruce
