What's it worth? Rare datsun pickup 1936-1940 kingcab short bed

Try listing it on an auction site like Bringatrailer.com or place an ad on Hemmings with "best offer" and fish for leads. You could also get it appraised by some auction listing companies like Mecum or Barret Jackson for a fee.

A few hundred thousands if it's a one of a kind. Just have to find the right buyer.

don't get your hopes up that would be a limited market , just because it's old don't mean it's valuable

I agree I really don't know what I have... think this antique would qualify for gold in the "head turning" category

Rare is only one factor, desirability is another. If this car is super rare Nissan might buy it. I am guessing it is worth less than $50,000 at auction.

Look for the Nissan Heritage site. They don't have anything like it.

chop it , make a custom rod , it has good lines and no one will know what it is , think about what it would get restored at auction
