It IS an original. 1863 model, dated 1864. Rear sight and ramrod are missing. The receiver plate is fairly bright and shiny, can clearly see all markings and the eagle clutching arrows and a tree branch in its talons. Just barely can make out the markings that were on the stock with a loupe. Do you think it would risk damage to just pop musket caps? I really didnt want to try reefing on the nipple to get it out and clean, I was trying to get through without disturbing it. Seems strong though, all the screws turn easily, and spring catches that hold the 3 barrel bands all work nicely, I have removed it from the stock to clean it. Havent used anything abrasive, just some wd-40 and a soft cloth.
