The Stovebolt Site Forums The Parking Lot Tons 'o Fun canadian gmc serial number decoding

I have searched and can not find the details to decode a 1949 gmc canadian 1 ton pickup (i think 1949). The tag is as follows

model 9434
s/n 994340307L

paint 932

anyone have a location I can get info on this truck... or someone know what this data tells me about the truck?

Thanks for help...
