I know where you're coming from being broke in the winter. The truck looks pretty good. She must have had a run in with a tree branch or something. Looks like there are a few spare parts there too. Not to mention the radio laying there. They must have been collecting generators for a while. I counted 4 maybe 5 in there. Hope you get it.
I bought a panel about a year or so ago about in the same condition with two extra V8 flatheads for $500. That truck will need a lot of work to bring it back.
As a parts truck it would be worth at least $500. The radio is not stock so it wouldn't be worth much unless it's from another hard to find car or truck. the Magic Air heater could be worth a few bucks, maybe $50, if it works. The big jewel is the panel truck seats. Very hard to find an original driver's seat because most were discarded for modern buckets and even harder to find a stock passenger seat, many trucks were ordered without a passenger seat because it took up valuable room.
The back doors should be worth a couple of hundred if they aren't too far gone, they're almost as hard to find as the seats.
The flathead might be worth a hundred, maybe a little more it it's stuck. If it spins over, which I highly doubt just by looking the pictures it's been sitting outside for a long time, it could be worth $400-500.
Although the parts might add up to more I wouldn't give more than $500 for it, hopefully your friend didn't give more than that for it.
Bob's was pretty sad, but the barn doors and complete roof found their way to my place. I'd guess that Bob escaped without taking a loss on his. I don't think at $450 you'd get hurt, even if you cut it up like Bob did. Stu
