Just had another closer look at this bike. It still has some original parts on it. Galaxies almost always came with GB bars and stem, and Weinmann cetre-pull brakes...and very often Wrights saddles. The top model with this frame, in the 70s - the Super Galaxy - was equipped with a TA double chainset and Suntour VX-GT derailleurs, often with the ratchet-type D/T levers..Lyotard pedals. The wheels were more often then not, L/F Normandy hubs on Weinmann dimpled rims.
Talk of Lyotard and weinmann in the same sentence reminds of a couple of pairs of 1930 Lyotard concave alloy rims - Weinmann style - that I saw in France quite recently...NOS. Now those are RARE !!!
