DISRAELI DOCUMENTS

New Cycling May 1981 - '81 Derailleur Collection
page 143 - scan 112 of 134

My rough translations of the photo captions, clockwise from top left are:

  • (Part) lever
  • (Part) mechanism
  • Complete set 1912

I think the Prével d’Arlay P. d’A derailleur was released in 1908.
