I have recently acquired a Richland Arms 1859 replica kit. It has sat in a drawer for 20+years and has a lot of surface rust and one badly rusted nipple. I am unable to disassemble it at this time because of the rust. I am unable to find any information on this company. I want a spare cylinder for it and don't know if there are any available or if a cylinder from another manufacturer will work. Any help or suggestions would be appreciated.
