I’ve seen it, worked on it, given advice on how to preserve it, pushed him to show it in public for people to see it. His name is Lee and back in the 50’ thru the 70’s, his father in law was a big wig at Chevrolet in Engineering. Lee and his wife got her father’s demo. Back window is original, the grill and gas cap emblem were restamped, it’s got some “experimental parts on it”.
