Check eBay for comparison. They have a lot of stocks in excellent condition. I paid $215 for a brand new in the box 1100 set not too long ago, but it had cut not impressed checkering. That is my favorite style of Wingmaster stock set, and it is what is on my 1976 version. I wish I knew what to tell you, but it is worth whatever someone is willing to pay for it. If you can find someone who is looking for exactly that, I would think you might get $100 to $125. Good luck.
