I had an 1873 38-40 also that I bought when I was young.
It was in fair to good shape and a lot of years ago a guy made me an offer I couldn’t refuse cuz I needed the money, wish I still had it.
I’ve got a First model 1873 44-40 that left the a Winchester factory the same month of Custer’s last stand. I’m also building a 32-20 out of new and old parts. Very cool rifles.
