Your father re-worked some grips for me over the years and the last pair was some real nice Mother of Pearl that I'd sent him. He profiled them so well I didn't have a thing to do when they arrived back here in Canada. I'm fairly sure he's still working on some fine Single Action Colt grips where he is now.
God Bless your dad. He was a fine gentleman with some real fine guns. Good luck with them all.
