Tim,
Thank you for your response. Yes, it is a 53 Chevrolet 3100. I have just returned from talking with Sherwin Williams. They don't have a color card, to look at. They suggested looking on line. Find a Hammertone/Hammerite, color card. Then, they might be able to order it in. If anybody else has found a better source, I am very interested in hearing about it.
Thanks again,
Rugo
