Drew,
First off, thank you for all you do here for the SxS community. For the sake of correcting an error I want to point out that I have objection to the first gun listed as a Baltimore Arms Company. Baltimore Arms models have scalloped breeches and the barrel flats follow the watertable profile. It is hard to make a definite identification of the pictured gun without more features, but I believe it to be either an N.R. Davis or a late model Torkelson.
