Reproduction decals to place on the bow deck are available in the WCHA Store. The large decal that is sometimes seen on the side of the hull wasn't used on a '40s canoe.
If people haven't jumped in here right away with the pictures you need, be patient and it'll happen. It could be the Holiday Mindboggle. You may want to try using the "search" function to see what comes up. There are several longer discussions on war-era canoes. Some of the changes that happened because of WWII didn't take effect until 1943, but these discussions may help explain things you might run into when working on the canoe-- such as use of steel instead of brass or copper, if this is what you find on your canoe.
