Just found an old Simplex Rigidex ³blue label² rear derailleur for a four speed set-up.
Fellow CR list member Peter Brueggeman has also identified this item as the Simplex "Grande Tourisme" rear derailleur.
The derailleur requires a clamp on or braze on two bolt chainstay mount of the kind used for Simplex or Cyclo Benelux or French Cyclo derailleurs.
Those clips and parts can be seen in a 1962 Cyclo Benelux Catalog 628/G/S (page 12) that is available on line.
The following is a link to the catalog page as shown on the Disraeli Gears
website ( http://www.disraeligears.co.uk/
Any help locating these parts for a cool project would be appreciated!
Thanks and happy riding!
