A curiosity - notice how the name is wearing off? That's because it's added after the regular decal process. National would make this with blank nameplates, so you find many with different "names" and the same decal pattern. And often the decals look OK, but the name is worn off.
Sometimes you can figure out who the reseller was, but not always. And resellers often switched the MFG they were buying from, but kept their badged name.
