I’d like go take that gun apart. There’s a leaf-spring on the back of the hand that I’m curious about. I’ve got a similarly designed tevolver with that spring broken. If I cock it while it’s pointed downward, gravity pulls the trigger down and locks it at full cock. Held level, or higher, neither half-or full-cock pawls engage. Cock the hammer, release, and it falls on the primer.
Someone needs to go down for the live ammo, at least.
