So, if those are Super 68 brakes, introduced for the 1968 model year, I wouldn't expect to see a Record rear derailleur and the 151 mm BCD crank, unless the brakes were replacements. Enlarging the pic, it looks like they say SUPER 68 on the arm, as opposed to the BREV 453949 of the Model 51 brakeset.
