According to an OLD post from Thor 50 and GMCPaul, that is an Oil Bath Air Cleaner.

Oil Bath
An oil bath air cleaner consists of a round base bowl containing a pool of oil, and a round insert which is filled with fibre, mesh, foam, or another coarse filter media. When the cleaner is assembled, the media-containing body of the insert sits a short distance above the surface of the oil pool. The rim of the insert overlaps the rim of the base bowl. This arrangement forms a labyrinthine path through which the air must travel in a series of U-turns: up through the gap between the rims of the insert and the base bowl, down through the gap between the outer wall of the insert and the inner wall of the base bowl, and up through the filter media in the body of the insert. This U-turn takes the air at high velocity across the surface of the oil pool. Larger and heavier dust and dirt particles in the air cannot make the turn due to their inertia, so they fall into the oil and settle to the bottom of the base bowl. Lighter and smaller particles are trapped by the filtration media in the insert, which is wetted by oil droplets aspirated thereinto by normal airflow.

Oil bath air cleaners were very widely used in automotive and small-engine applications until the widespread industry adoption of the paper filter in the early 1960s. Such cleaners are still used in off-road equipment where very high levels of dust are encountered, for oil bath air cleaners can sequester a great deal of dirt relative to their overall size, without loss of filtration efficacy or airflow. However, the liquid oil makes cleaning and servicing such air cleaners messy and inconvenient, they must be relatively large to avoid excessive restriction at high airflow rates, and they tend to increase exhaust emissions of unburned hydrocarbons due to oil aspiration when used on spark-ignition engines.

Back when I worked at an ESSO (Pre-EXXON) station, we hated oil-bath air cleaners. Servicing them was part of an oil change. They were usually found on the older cars/trucks we serviced. For the most part, they were last used on FOMOCO stuff in '56. GM used them until the early '60's, depending on the engine. 235 six-cylinder engines had them until the 230 engine came out in '63, at least in cars. My '65 C-10 had one, though. MOPAR trucks used them into the '60's, too.

The filter media was usually excelsior, a fiber that looked like a pine straw that was woven into a mesh. Servicing those filters meant disassembling it, washing out the old oil, rinsing the dirt from the media, then adding new oil to the "Oil Fill Level" mark, and reinstalling it onto the carburetor. Some had a clamp that attached it to the top of the carb; others used a long stud with a nut on top to hold it on. If it was a hot day and the oil change was being done on a hot engine, it could become a bit dicey. There's been more than one of them that got dropped onto the engine.....
