The first picture shows the original Simplex Prestige derailleur fitted to the bike. I changed the body to a newer version but had problems with the mech taking up the chain slack. This is evident in the photo on the header. This was eventually changed back to the Suntour mech which was originally on the bike back in 1973. Also evident in the second photo the rear-ends have had the paint removed and restored back to the original look. A new inner and outer cable was also fitted.
The Stronglight double chainset was just cleaned. The existing 54T set up harked back to the days of time trialling and the 42T ring was added when I moved to Derbyshire!
