Greetings---
Here is a NOS CYCLO BENELUX rear derailleur from the '50s.
It looks rather like a Mark 7 from the mid-to-late '50s, but I'm no expert on all the Cyclo Benelux iterations and really don't know. This derailleur says it is built for 4-speeds on 3/32" setups and 3-speeds at 1/8".
I was planning on using it to finish a project which is now on ice. Please note that this is not the long-arm Cyclo Benelux Tourist derailleur about which I recently posed some questions to the CR list.
Condition: NOS, never mounted. Perfect except for some loss of the black surface on the coil band. Strong spring and linkage.
