OK, so I bought this radiator and shell on ebay. It was listed as a Chrysler item, but I don't think so. It's not a honeycomb, but a tube and fin type and Mopars were honeycomb in the 30s. It has curved fins that follow the radius of the shell from side to side. It also has a raised circle at the top front which has a small spur off the edge at about 2 oclock on the dial, sort of an upside down Q. Interesting piece for my 29 DeSoto roadster, but where did it come from originally? Foreign maybe?
come on now, somebody here must have seen one of these in the last hunnert years or so.........help a dummy out!
