FQ, a little searching would have probably found SEVERAL companies that did the same thing where you were at the time.
You don't get a new stock, they custom bend the one you have. If you have a high end blaster why would you pinch pennies on accessories ?
Granted you didn't know about it at the time, but I want to make sure that you understand you got rid of heirloom guns now worth several thousand $ each, and back then the fitting would have cost about the same as what you laid out in cash to trade, maybe less 
You may now go kick yourself, repeatedly 
Actually no kicking. I could have only afforded to keep one. All of them were well built but plain Jane. I did prefer the Webley in looks and function, but the stock had a small crack and would have had to be replaced eventuallly (maybe by me, maybe my grandkids), but it was a time bomb which is why is was $2k rather than a $10k gun. The thing is, by tradig these I discovered I like SxS a lot better than O/U and I got to shoot some nice ones. If I could have kept them all I would have, but given my budget, one expensive shot gun was all I could keep and the one I have is perfect for me.
