I have a Browning 1910 .32 acp that is nickle plated and has three marks on the grip safety. Hard to describe but look as though they may be Chinese/Japanese. Rest of gun is properly FN marked but I can find no reference books that show or mention marking on grip safety. Top mark looks something like a distorted set of football goal posts. Center mark a straight line with slanted ends going downward with upside down t through middle of bar and bottom look like a K. Serial # 435XXX. Any help?
