I'm no expert, but I'll tell you what I know. The model 61 carb (Massey 44/55) had a 1.25" butterfly with a 23mm venturi. The model 62 is identical on the outside but has a 1.4375" butterfly with 25,27, and 29mm venturis available. The Zenith Bendix carb (I believe used on a GM truck in the 40's) has a 1.5625" btfly with a 28mm unit. This carb was application specific so it didn't come with an adjustable load jet, and I doubt any venturi options. However, I think 30mm would be possible with machine work. I know nothing about the really big Zenith's.
