R51/3 Air Filter
The earliest type, which I've never seen in person, has several openings around the circumferance of the unit, and they can all be closed to choke it. The type that came with my 1953 R51/3 is a clamshell affair, with a separate element that goes in between the clamshells. There's an air openning in bottom rear, and a choke lever there as well.
I believe the paper element cleaners didn't come in until the R50/R60/R69 bikes after 1955.
