Is the broken butt plate a plastic one or is it made of horn.. If you look closely the horn plates are not pure black, usually.. Most have some streaking. If it's a horn plate you may find one on Ebay, gunbroker or one of the other auction sites in a lot of buttplates or perhaps at a gunshow but I wouldn't bet on it.. If it's a plastic one, just order one from Brownells or GunPartsCorp. Gunparts may even have a horn one.. Of course any plate that's large enough will fit and Brownells sells a plain black plate for that purpose. Also a recoil pad might be fitted.. I would fix the old plate if it were horn. Epoxy the 2 pieces back together using the screws and holes to hold them in place. A bit of wax paper will keep from gluing the buttplate to the stock. After the glue has set I would reinforce with a bit of epoxy and some glass fibers. The horn plates can also get a bit expensive. Letr us know how it works out..
