Our Assessment: This Erskine Allin altered 1865 conversion is a first model example, an early iteration that paved the way for the seminal Trapdoor rifle. They were older muskets converted to cartridge firing rifles, this one being chambered .58 Rimfire. At first, the barrels were re-lined, but often that lining would separate after firing, and in the end the barrels were replaced entirely. The 1865 holds a fascinating place in the history of military rifles as it serves as a bridge between the old weapons of war and the new. This is a neat piece for the Trapdoor completist. Good luck and happy bidding!
