Hello Y'all, My aunt recently gave me my grandfathers guns she inherited. Long story short, she sadly stored them in the garage for a couple decades because, 'I don't allow guns in my house'! Slowly restoring them to workable condition, I finally got to this black powder rifle. Searching the webs and your forums I am still at loss on what it is, or where it came from. So I'm reaching out to you more knowledgeable gentlemen and ladies to help find out what it is. I haven't taken apart the rifle yet, but with your suggestions I will. There are no markings on the outside. It's barreled, and the hammer/trigger still works. If y'all need anymore photos or information don't hesitate to ask! Also, any suggestions on how to clean it and get it back up and firing would me great! ATW!
