Looks like a fairly complete, mostly original truck! Is it an ex-Norwegian vehicle? I ask because it appears to have several extra holes in the same locations mine had, from their modifications. The serial number on the frame is located under the drivers side front fender. It should match the data plate on the glove box door if it didn't get swapped at some point. I see someone added an electric fuel pump, and maybe a civilian air cleaner? The voltage regulator is a replacement also. Looks like your truck is probably a late 1943 or later model. I believe it would have been 12 volt from the factory. Where in GA are you? I'm just north of Atlanta.
