Let me post the pictures and then I'll tell where it came from and such. It was made in 1875.
OK, the pistol belongs to a man and wife that my wife and I know. It was inherited from the man's great grandfather who had run off to work on a horse ranch up in Montana or Wyoming at the age of 14. I'm not sure where he got it, but It's intact except for needing a new trigger, trigger/bolt spring, hammer spring, and maybe a new trigger. All small parts.
My wife and I asked them if we could take it to the Antique Road Show Saturday here in Omaha. We'll see what the old Colt is worth. Anyway, it's an early one that could be repaired with not too much expense. Notice the three notches cut with a file next to the bottom back strap screw. Wish it were mine. The man's son's don't care for it and so maybe, when he and his wife need some extra money, They'll be willing to sell it to us.
