The monogram is "JCB" in a triangle insert, too bad it's not TCB with a lightning bolt.
Who would "TCB with a lightning bolt" be? "GSP" is the only monogram on a RM .357 that I know the meaning of, but we all know where that one is.

That is one helluva find. I hope it didn't hurt too much. Clean it and shoot it is all I'd ever do to it. Wow.
