My 1929 RK oil pressure is approximately 1/10th of speed in mph.
I think the specification is between 2 & 4 psi at 30 mph with the engine hot.
I have fitted a Bullnose Morris pressure gauge which is calibrated up to 10psi. When the engine is cold the needle goes right round and hits the stop at zero coming from the other direction. My guess is well over 30psi.
That's OK because the gauge says "Guaranteed to withstand an overload of 200lbs".
The car cruises happily at 50mph. Easily reaches 55 with 60+ downhill.
