This used baggage carrier manufacturer is from and well known in Germany called Krauser. OEM supplier for BMW in the 1970s and 80s.
This is a real crap !
It is made from modular components and individual fixing plates to match the bike.
I have bought a Denfeld carrier (Kawasaki OEM in Germany in the 1980s). Mounted that to Maria’s LTD. That is made as single-piece from chromed tubes. That is so much better than the Krauser.
The cases themselves are different and either fixing to the carrier, the hinges, the locks, the seals, everything is better with the Denfeld ones and Krauser is far behind !
This is related to the available stuff from the 1980s, not a judgement over current stuff that is or might be available now.
