Not sure what engine that might have come on, but may be from a car, based on the offset to the carb to clear the lower hood on a car. Might be an oil bath, but hard to tell from the angle of the photo.
[on edit] Google Lens comes up with this: The selected region displays an elongated, offset metal air cleaner housing from a classic inline-6 engine, commonly found in vintage mid-century Chevrolet or GMC trucks. Also: Parts Overview Type: Vintage offset air cleaner housing / oil-bath or dry filter assembly. Application: Designed to clear the brake booster or steering components on inline-six engine bays (such as Chevy 235 or 250 straight-six motors). Condition: Shows aged black paint with surface rust, typically restorable or used for period-correct engine restorations.
