Miller & Ky Jon, My Optumus quality piviot lever gun has bushed firing pins and a three position saftey. I'm really not sure of the manufature date on my gun the serial number says pre 1890 but the rib style says its a later gun so who knows.

I did have Jack Haugh make new firing pins for my gun because the originals were not what they could be after 115+ years. I also had him add light coil springs to the pins so help them retract. It will give the collectors something to wonder about 50 years from now.
