A friend picked up what appears to my untrained eye to be a Ruby Pistol. It is of .32 cal and in excellant condition. On the left side of the slide is "AUTOMATICA ESPANOLA-PATs 62004 Y 67577/ "BUFALO" CAL 7.65. The grips have an entwined C in a B, there is a Buffalo head in a circle on the grip panel. The only other mark (outside of some proof marks on the slide and frame) is the S/N (170X) on the right side of the frame. It looks to me to be a copy of a Browning 1910, but what do I know.... Any info would be appreciated.
