It is spelled with one "R". One small problem with me living way down here in the sticks is, there ain't nowhere for me to take it to be appraised.I have to do all my research on the web or try to find it in a book. I have another item that came with the gun that I believe to be something "rare". I'll post a pic and see if anyone can identify it to be what I think it is. It's something you don't see everyday, well I don't anyway.
