Beautiful old pickup truck, I have a 1947 WF 32 Dodge 1 1/2 ton grain truck still on 6 volt , I noticed you still have the original honeycomb radiator, love that body style.
Mine must have been an early 48 cuz it was registered as a 1948 but it has this body style like the one in this video. The bed in my truck had the diamond plate metal bed rather than wood. And I had the same problem with my speedometer with that Center ring falling off it never worked the whole time that I owned it which was from 1967 to about 1975. But that truck brought all the lumber up the mountain to build the house that I'm living in now.
