Puch Monza Replacement airfilter

Replacement airfilter for a Puch Monza (austrian version). See attached picture for how it's mounted. May require light sanding to get it to fit in the frame hole. It's been on my bike for several thousands of kilometers and hasn't broken and stays snug in place. Cut some filter fabric to size to put inside the airfilter. This fits well with the TPU airfilter-carburetor connection rubber on my profile. The connection rubber is made for Dellorto PHBG carburetors
