I just dismantled an old cab for parts. I also had never seen these little gutters on any trucks. I think they must have been an option. When looking at the photo you will see that the door has a vent window, this rain gutter would allow the vent to be open while driving in the rain. Because the vent windows were only introduced around 1951 I would say that these rain gutters may have not been of any use because doors prior, were only available in full glass. Not absolutely sure on the introduction of vent windows?
I think they look pretty cool.
