And a wee bit of carburetor trivia:
Zenith had a two-barrel carburetor at this time (type 28ADA) but it was heavy duty and EXPENSIVE! For this reason, these units generally only were used in industrial applications, and heavy duty trucks (Autocar, Mack, etc.).
Zenith and Stromberg were owned by Bendix Aviation (Bendix was [past tense] to Zenith or Stromberg as GM is to Chevrolet or Pontiac).
In the mid-1950's, Zenith wanted a light duty 2-barrel carburetor.
So the engineers at Zenith and Stromberg got together, and settled on the upper 2/3 (air horn and bowl) of a Stromberg WW, and Zenith cast a new throttle body out of aluminum, with linkage differing from that of Stromberg. The new carburetor was called a Zenith WWZ-10. First production model was 1957.
