I thought I posted this a few years ago, but couldn't find the ad. I got this radiator and grill shell along with the project car I bought (28Pontiac). Its clearly for a ford, but beyond that I don't know. I have the original box that the pair came in. I do see some wear on the radiator from the box. Selling for $325 plus my shipping cost plus paypal fee.
Someone asked for dimension - here they are: The width is about 19" plus or minus 1/8" The height is 24 3/4" except where the bottom hose connector is, which adds about 1" The radiator appears to be brass
