I like these 531-throughout bikes a lot. Parts would be comparable to an Alex Singer or rebuilt Rene' Herse. Year is 1974-1976/7. This one may have the maillard 700 competition hubs and super-narrow weinmann 22mm alesa 27" jclinchers, you might want to enquire. Should have bluemels fenders, jubilee gears, rare and early dual pivot "Weinmann Symmetric" brakes, etc. Since this is an unknown model, it often sells for a low $$$ price.
