I recently bought an 1873 Springfield trapdoor. The auction said that the bore was pristine (It is) and the rifle is in good working order. It also said that there was no finish on the rifle. When I recieved the rifle, I found this not to be true. It appears that it is nickle plated. I removed the barrel from the stock and the finish looks as good as the the day it was done. There are areas where the finish has come off but this is really no big issue. My question is has anyone seen a trapdoor like this before? I am new to the trapdoor scene and have only seen the blued rifles. This rifle is in great shape and I have a range day next week so I have loaded some BP rounds with 405gr RNHB bullets. Comments?
