Your entire body has tetanus

now it’s got your prints you -idiot-

Take it to the police it’s probably a murder gun

That's a Schofield!

Its a S&W top break revolver. A schofield doesnt have that curved portion in front of the trigger guard, S&W does. Very cool to find

I reckon the rest of the guard just rusted off?

I see what you mean now. Eh, well. Very similar to the S&W Model 3

(I'm still convinced that it is.)
