'76 or '77 grand record came to me with 531 decals on the fork, campy drops, suntour cyclone gearing, sugino arms and atom 700 pedals. it had rigida 700c rims on campy nr hubs i assume were an upgrade. i swapped out the gearing, headset, and seatpost (26.6) for campy nr/sr. the fork crown was french sized when it arrived (later milled) and the steerer is standard diameter with french threads. the bb shell is swiss with a sakae bb as found.
bb shell s#: 3606 443 701
edit: after researching my latest acquisition, i've realized my gr is either a '76 or '77. moto started using suntour cyclone on its jubilé in '76. as my gr came to me with this instead of campy gearing, it almost has to be a '76 or '77. by '78, the gr no longer looked like the gr. gone was the traditional trim and campy nr componentry altogether.
