No, the radiator is performing great. I am asking about original issue radiator caps from a correctness standpoint.

I believe the original radiator caps were stamped S. M. CO. with a patent number around a large domed rivet. One ear might have R-7 and large, raised words on the perimeter were TIGHTEN and REMOVE SLOWLY with arrows. However, I am not certain of this as so many reproducers have several caps they claim as "exact reproduction" which usually aren't.
