My favorite shotgun for clays and quail is an beautiful old Ithaca 900 SA 12ga. My last outing was a heartbreak when I got home and found a good excuse for some very bad shooting. The stock is split on both sides of the grip and the receiver is set back into the split stock by about 3/4 inch. This is actually an SKB product and I am wondering what are the chances of finding a replacement stock and how much fitting might be required. I'm not a big shotgun guy so any info will be a help.
