Hmmm, its probably worth something between $500 and $5000, or maybe even more?
It is impossible for anyone here to make a useful guess.
It would be ridiculous for you to heed any number given that is based on such limited knowledge about the vehicle.
It is understandable, however, that you are asking this question - you do not know, and you need help.
How much is it worth to you to find out? Hiring a local appraiser is your best bet on obtaining a somewhat realistic estimate. People in a local car club would know reasonably priced, competent
appraisers.
Ask the appraisers for a couple of references from customers who wanted information on pre-1960 trucks. Call those customers - old truck owners usually like to talk about their experiences. If they liked the information from the appraiser, go with the appraiser.
It has been a while since I had to hire an appraiser, but I guess they might cost somewhere
$150-$350?
Or, pay nothing, and get interesting and sincerely thoughtful advice here.
