Hi Jeff.
I saw a Star radiator and shell for sale at the Portland, Oregon swap meet some weeks ago. It looked like it was in pretty good shape. I have no idea what year or model it was from, but it did have a Star radiator badge on it so it was defintely a Star.
I got a card from the seller.
The fellow who had it is Jack Hagglund, email jacksplymouths@msn.com and phone 206-730-5132. The area code of 206 is from here in western Washington state
Good Luck.
Bob
