I am the new owner of a Model 38 that has what I believe to be ivory stocks. One stock panel has a crack across the stock at the escutcheon, probably caused by over- tightening the stock screw. It doesn’t appear to go all the way through, and I’d like to keep it that way. I will get a new set of J frame stocks from Altamont, and retire the ivory stocks. Any repair advice is most welcome. I never had a pair of these before and know next to nothing about their care and feeding! Thanks, Hank.
