Great information, thank you. So the term "prototype" really does not apply to these trucks, but rather trials or limited production. Re the 1940 vs 1939 dates, the commercial vehicles were always released a little early before their actual model year.....I suspect that is why the parts may have the 1940 code to them. I'll keep my eyes for a more definite date on anything. Unfortunately, the radiator, which often have very precise dates on them, does not have the usual little plate attached to it. I have my doubts if it is even the correct radiator.

Front axle is indeed a Timken, the name is cast into it. Any parts I have removed from the front axle, like bearings etc, that have part numbers, have all have the Timken name but Ford part numbers. I'll find out soon enough if the standard Ford kingpins will fit this truck.

I'll bring the camera to "work" today and get some photos. I'll quote the term "work" because it is not really work when you enjoy it this much.
