For now,
Clean it up and get it in good condition mechanically BUT DO NOT RESTORE IT,OR PAINT IT. Take it to a Early V-8 Meet. The guys will go nuts over it.
At a later date, the car can be restored but after that, it can never be un-restored.
The good original unrestored cars are really getting the attention and are bringing excellent prices. I have an old "Patina" '32 Hot Rod that looks way worse then your car. Ten years ago, I would not have wanted to have it parked in my driveway but now everybody really gets excited about it.
As for value, it is hard to say. I am thinking somewhere between 20 and 30K. There is a car sort of simular to yours here in Pasadena that is currently on EBay.
That is my opinion,
Chris
