Cal 40-90 Sharps. This is the 40-90 Sharps straight. According to the Porter 1885 Survey only 13 were made in this caliber. This is a #3 oct bbl with a low serial number being just over 1k. Nice cond overall with an aged patina to the metal. Some wear and flaking to the bbl creating a grey/brown color. Forearm is nice fitting and in good cond. Buttstock is nice fitting and has a repaired crack at the toe. If you like 1885’s in rare calibers this is the one for you!
