question for the Allegro experts -
have seen a good number of the Special model from the period between the late nineteen fifties and the early nineteen seventies
in all cases recalled if fitted with a headset from Verot-Perrin they would exhibit a chainset from the manufacturer as well, whether a 57, 63 or 93
so slightly surprised to see a Record chainset here
wonder if it may have been a replacement
