The PAV 100 was made by Kovozavod Semily, branch office Roztoky u Jilemnice. This is the same company the built the PAV scooter/motorcycle trailers in the Czech Republic. If you have any info on this trailer assembly, feel free to drop me a line and tell more.
We did a search for the PAV 100 and came across a bunch of pictures of the PAV 100 trailers. All the photos here are from this website that has some amazing pictures and if we could translate Czech, we're pretty sure they have some great info also.
