Hello, I have my granddad’s S & W .32 top break revolver. I don’t know a lot about it other than reading everyone else’s forums and finally able to decipher the serial number (228555).) I wanted to restore it (just for looks and for myself) but was advised not to do that for authenticity reasons. I would really like to replace the broken mother-of-pearl grip but I can’t remember what type of grip it is (“j”, “k”,etc) nor can I find them. Any help with info on this firearm and/or grip info would be greatly appreciated. Thank you. KdHill
