I have a ton and a half farm truck with a grain bed. I was not aware that there were any 'series' associated with this model. For what it's worth, I 'think' I have a 1946.1 model. It has the same body and appearance as the 1941 and later models, but it's always been titled as a 1947. I'm pretty sure that my Dad bought it new in the spring of '47, but it's NOT the same style as the other '47s...it's SO much cooler...[Grins] This has been in our family since new...been in storage for the last quarter century and is just now being restored...neat to hear it running again...
Thanks for that interesting link to pickups...time$ and dollar$ $ure have changed..!
