Oh, ok. The pic makes it look like the cheek piece was on the right side of the stock is all.
I wonder if someone that was good at working with wood could drill it and put a dowel/s in glue it back together.
When my daughter was little she thought it was fun to sit and one of our lower kitchen cabinet doors and swing back and forth on it. Until one time when she was doing that and it broke in half length ways at about a 30 degree angle. I took the two pieces to a guy that had a little cabinet shop out of his home. When he was done I couldn't really even see that it had been fixed, it looked that good. He told me he put dowels in then glued it back together and sanded it smooth. He told me it'd be stronger than it was before.
Getting something new is always cool but hopefully you'll find someone that can at least put it back together for you.
