Vintage Cyclo Benelux Rear Derailleur

• I believe this is a Mark 7 (Mk 7) model from the late 50's or early 60's
• It is marked as being designed for either a 5-speed / 3/32" or 4-speed / 1/8" setup
• Chain pull mechanism
• Toothed upper idler, smooth lower idler
• Mounting bolt, b-screw, and cable pinch bolt are all present

Condition is USED/GOOD:

• Scuffs and scratches from use
• A bit of wear to the smooth lower idler pulley
• Scratches to Benelux logo
• Pitting to chrome in various places
• Everything appears to be functional
