looks good, I say bring it home.
Could bring a few thousand dollars from the right buyer.
Assuming no or very minimal rust and it runs and stops, I guess less than 5,000 would be fair but high, and it would be great deal for less than 1,500. It's hard to give a price without seeing it or knowing what others in the area bring.
Edit: After seeing more on the condition I say well less than 1,000, probably 3-600....
