'AFJuvat' - That looks like a correct late model 1873 to me and would probably be a nice 'Shooter' or representative SAW piece.

The stock markings are interesting, but, a mystery to me.

IMHO - Cabela's $900 price is about $200 higher than I would expect to pay at a Gun Show for a 'trapdoor' in that condition. (It does have visible minor cosmetic flaws to metal finish and stock).

I like to see such a rifle first hand to be sure of bore condition, correct function of lock and action, and condition of Stock.

Dick Hosmer's advice to be patient and monitor selling (and 'sold') prices on GunBroker is golden.
