Hi Tim, thanks for the help. I think it is a '49 3/4 ton. It has the gas tank in the cab, lever action shocks, 8 lug wheels and a long bed. Does that means it has to be a '49 3/4 ton? The headliner is two pieces held in place by screw in metal strips. Does that mean its an early '49?

There is a red plastic knob between the defroster and brake release that says "Flarestat 105" on it. What is that? 4-ways maybe? If so, they don't work.
