Resilion Crimson Star derailleur gear

The Resilion company was situated at 200 Liverpool Road London
N1. The 1958 Crimson Star gear worked on the same principle as the
Simplex Tour de France and the Benelux Mark VII in having a chain
toggle pulling the changer towards the higher gear (smaller sprocket).
This was the last derailleur gear produced by Resilion. The
nylon pulley wheels, red behind the logo and the crimson star badge no
doubt gave the gear its name.
Resilion Crimson Star gears were British made and common
in the early 60's, especially on lower end mass-produced lightweights,
Normans, Phillips etc. The red jockey and tension sprockets were very
simple to remove. If I remember correctly they had no cones
fitted which simplified care and maintenance. The gear arm was pivoted
so that you could swing it out of the way to help in wheel removal.
Think you could easily get the wheel out on any cog because
of this. The toggle chain was shrouded for protection against damage
(see advert scan).
The real beauty of this gear was that they would operate on either 1/8"
or 3/32" chain and were suitable for 3,4 and 5 speed blocks. Absolute
godsend for us young tandem riders when we junked our old twin wire
Cyclo Standards and with a Baylis-Wiley Freewheel hub unit fitted sheer
They could handle a ten teeth difference typically 14T to 24T. Chain
tension was regulated by the spring on the traverse arm. The data below
is from Resilion:
'Ease the eye out of the notch in the ring inside the gear arm and turn
the spring clockwise five notches from the slack position of the chain.
The toggle-chain guide on the outside of the gear arm should be screwed
right in for 3 speed 1/8" and 4 speed 3/32" gears. And screwed out
until the first thread appears for 4 speed 1/8" and 5 speed 3/32"
