The pressure cap looks and is like automotive caps of the era. 7 PSI it will have cam lugs on the outside of the lip. If it is non pressurized, it will be much bigger and is very similar to the fuel cap, which has its cam lugs inside the seal ring. Jim
 
The radiators where the fuel cap fits are only on the early-early models of A/B/H/M. By the time the C came around they all had the modern automotive radiator cap.

I believe you can use a pressure cap, but no more than 7PSI.

Tractor supply also sells a non-pressure radiator cap, also advertised as an oil fill cap for a Ford N-series.

Diverging from the original question, but the Super A of that time did not have a pressure cap. It used the older style cap that fit the same as the gas cap. The Super A1 had a pressure cap.
