Cheese - nice looking Harley ya got there. For a replacement military stock I would look at SAMCO, SARCO, or Gun Parts corporation as they have the largest mil-surp inventories, but also look to our sponsor list - I know that at least one of our sponsors makes gunstocks and may produce sporter replacements for the 1917/M17 and another of our sponsors is a large supplier/distributor or gun parts and sporting equipment and they may have something you can use.
