Don,

...excellent eye and good catch, but that debut year would be 1976:

Technically, this is a model GC-100 crankset from the initial Shimano 600 series offering circa 1976 through 1977, constructed from 17S Drualumin with Almite finish, available in 165 or 170 mm arm length, to accommodate 95 mm BCD chain rings sized 30 through 53 teeth which were constructed from 14S Super Duralumin (...double ring standard with triple ring configuration optional by request).
