Ivory a frequent forum topic maybe my Ivory show & tell of interest. Most of the grips are from when I was working in Africa Belgian Congo in 1951, had local ivory carvers copy original Colt & S&W grips. Decor on all is DIY. Tusk ends I probably bought at London street market Porobello Road in 1950-60s. Hackberry wood is a chair arm I made from when a tree I played under as a kid died & we cut down & I've made grips from.
