On short notice, I would give Dick Greensides at Pecatonic River a call about a replacement stock. If nothing else, he can use the existing stock as a pattern to make a new one of walnut for you. He can do as much of the finish work as you want to pay him to do, or send you the pattern stock to do the final finish work yourself.
I chose Dick, among other stockmakers, because I have found he will work with you on Short deadlines in situations like this.
Most laminated stocks are more glue than wood, and are made under pressure. If there is a flaw, it will be visible to the educated eye. Typically, any failure will occur in the wood, not the glue, but there can be and are exceptions.
I have a client who makes many of the laminated stocks used in the gun industry, but I have never heard that he ever made stocks for MLers of any kind. If you are set on trying to replace your stock with a factory, Laminated stock, send me a PT and I will give him a call to find out who made yours for RMC. :thumbsup:
