It's an aircraft engine pressure carb so it's in the same category as those. That one has fixed size venturis instead of the variable or rectangular type. It was likely used on some intermediate size radial engine. Bendix/Stromberg wasn't the only company that made pressure carbs. That one looks like what the old Sikorski S-58 had on its Wright R1820 helicopter engine. It may be for any number of R1820 engines since so many were made during the war and after.

The Stromberg Aerotype in post #2 is an automotive type carburetor and it has a float bowl.
