I don't know if you've found a cover yet.
Cover for the
Cadet can be bought from a on-line shop in Germany that is specialized in parts and accessories for the
Cadet, which in Germany is called "Niewiadów N126". The cover is called "
Ganzgarage passgenau". The website is in German, but the owner speaks English. He ships abroad, but one has to request a quote for shipping abroad. I can't say for shure that he ships to the US, but one can only ask. We visited his shop last summer and bought a
"rain cover" for the roof lid (Hubdachstoff "England").
