Hot Rods Ford Flathead Intake Question

Does anyone know what the S cast in this intake stands for? I think it came off a 1936 motor.

 

Probably a better question for fordbarn.

Early aftermarket replacement manifold

 

Speedway Motors? No, not really.

 

It stands for Standard Automotive Mfg. Co. Los Angeles California. They manufactured replacement manifolds for early flat head engines.

 

You will find that S on a lot of A and V8 ignition parts, like pong plates and coils...S was one of several suppliers of ignition stuff as original equipment.
Bohnalite was the main supplier of aluminum manifolds and heads, and was a major contributor to a real revolution that we still use...180 degree manifolding.
This stuff came through Ford production routes and so was not conspicuously marked.

 

Thanks everyone for the info.
