Tim - All of my 56 and 57 Kodiak Specials are marked on the belly, but I wouldn't place too much store in the side of the bow that is marked as accidents happen in factories. There are lots of mismarked Bear bows out there.
The NFAA water transfer decal was put on many items by many bowmen in the 1940s through the 1960s. These guys were proud to be NFAA members. I have seen many bows with the NFAA sticker on them and have a few myself including a T/D Grumley Deerslayer.
