WTB/WTT a Simplex change fork. I dont have a date of introduction but guess
it was probably pre WW 2, Simplex produced a derailleur system very similar
to the Super Champion, or Osgear as it was known in the UK. I have located a
complete tension arm. I also have 2 gear change quadrants. Does any one have
a Simplex change fork so that I can complete the gear? I have Osgear spares
to trade. Can anyone help with a fork or images or any history from
magazines etc?
