Randy, from your serial number I'm guessing that your gun was made in the early part of 1918. As far as finding a complete forend and stock, like finding the proverbial "needle in the haystack". Is the forend missing and what condition is the stock in? The stock can be fixed if it is cracked, the forend iron would be the hard thing to find and fit. You should be able to find the firing pins or have a small machine shop make you a few. I don't think with this date that the firing pins are in bushings.
