In doing an internet search years ago for the PAV 100 trailer, the photos below came up. While clearly not a PAV 100, the fender appears to have the same 3 ridges as a PAV 40 scooter trailer. Based on the size and the dual mounting points on this trailer, they are believed to be another car based trailer. It appears to use a steel tubular chassis, and a fiber glass body. PAV trailers were manufactured in the Czech Republic, originally by “AVIA n.p”. and later by the “KOVOZAVODY SEMILY” company.
