You will likely be unable to find new replacement stocks; but you may find an old original stock on eBay, or one of the gun auction sites like gunbroker or auction arms. But if your stock is only cracked, it can be invisibly repaired with one of the modern expoxy glues and be stronger than it was new. Exaclty what will be required to repair the stocks will be determined by the amount of oil that has been absorbed into the wood and the nature of the cracked/damaged areas. I just had a double gun stock repaired that was broken completely apart at the wrist and it is now impossible for anyone to know that it was ever cracked; much less broken. I would suggest you find a good stock man and ask for an opinion.
