Stromberg Carburetor ID - Manufacturer Code Numbers
Most production carburetors from 1934 onward have a code number stamped either on the body or on a metal tag attached to the body, which identifies the car or truck and yearly model on which it is intended. In the 1930's this number was often stamped on the throttle body. Later carburetors - 1940's and up - have the number stamped on the top of float bowl.
