In the PNW, these trucks are all over the darn place. If it's worth $250 to you than it's worth $250 to you. I've bought them for less and bought them for more. Who cares what scraps worth? You don't plan on scrapping it do you? Don't let anyone else rattle you on what your willing to pay. Do what feels right and trust your gut!
Brad, I don't know how you could get that price in parts? I've tried parting out 1 1/2 ton trucks and can't give the parts away up here. If you can, I'm jealous!

Check the transmission for the lockout lever for reverse. If it has one it's a '47 as they used the non-synchronized transmission. If not, it has an sm420 and indicates a later year truck.
Good luck and keep us posted!
