This is my first posting and I'm new to the BP thing. So here goes.
I bought a custom built half stocked .50 cal gun. It has a browned octagon barrel, a maple stock, with a older looking buckhorn rear sight with NO marking on it anywhere that is visible. I did take it apart and the only marking are on the bottom of the barrel under the wood that is marked"GRRW". This is stamped on the barrel twice about 6" apart. Is this the makers initials of the barrel marker?
TIA
