One of my most go to rides, as well as being a machine Ive upgraded gradually over the years is this Worksop Sun, badged as a Snipe Prestige, the frame was originally a Massed Start 100 model. Progressively updated over the years, it currently runs a 15-speed set up using a modern Sugino triple...
Original spec was 999 Weinmanns, Simplex Prestige rear mech. Simplex front changer. Brooks B17 saddle, GB bars and stem. Shortie Weinmann guards, QR Large flange hubs.
Well worth doing up. Ive rebuilt one form just a frame and forks with some nice bits, tried to keep it relatively period correct too.
