I’m not well versed on SW models, but I believe this is a model 1905 hand ejector. It is in 32-20 and while it functions great, the bluing and surface finish leaves a lot to be desired. I bought it this way and kist don’t plink with it as much as I used to. I do have reloading dies, bullets and a decent amount of loaded ammo for it which the buyer will get first dibs on. No trades.
