I had noticed that there are no 44s too...
my 44 stakebed (bought on a ration stamp!) was listed in the 43's, and there's another 44 fire truck somewhere around here also listed in the 43s...
I know mine was assembled in 44... 9MS26-XXXX == made in febuary of 44 in Norwood Oh, long wheelbase 1.5 ton... probably a cab only at the factory as it was originally for windmill installations...
