My '37 engine looks exactly like Don B's. I'm pretty sure all the blocks and water pumps had the bypass hole. I believe a thermostat could be used in a car with or without the thermostatic louvers. The correct thermostat at the water outlet would assure quick, even warm-up, and the thermostatic louvers would further contribute to fast, even warm up and help retain engine heat when the car was parked in cold weather. My car is a 120 C and it does not have the thermostatic louvers. I wish it did have, but finding all the parts needed in good good working condition would be difficult. I think I'd need the entire louver assembly, the thermostatic louver motor and linkage, and the correct radiator.
