My bike is a 1950 M21 rigid. The parts manual shows an air filter but it looks like it may only fit with a monobloc carb? Was there ever an air filter for the 276 carb?

I've no idea what was fitted post war. But Burgess made a pancake filter to screw directly onto a 276. It has a built in rain shield and was fitted to some WB30's during the war. I think Hussein has one for sale. Ron
