Does anyone know anything about this guy, or the gun? Seem like a too good to be true situation to me.

He says it's been proofed, but I don't know enough about proofing marks to even know what to ask.

Also I haven't seen a full nitro 577 2 3/4" before, I thought that was supposed to be the light nitro version.

Any information would be greatly appreciated.
