I'd guess then that this one falls into the 1867 to 1872 timeframe (as did the fellow who owned it before me). But because of the J. Thomas patent (#324 of 1870) that was employed to secure the barrels to the action, it is clearly now post 1870, so... that narrows it down to just 3-years of production, 1870, 1871 and 1872.

This is some fun, eh?
