Radiator ID

[tomcarman]

Thanks everyone for the replies and help identifying it. The fins are in much better shape than the one in my avatar '32. There is a beautiful indentation where the fan hit it at some point in its past and it will weep a bit. How would I go about testing this one for leaks and proper flow? I imagine start by pouring water in it with the lower hoses plugged but what about pressure and heat?
