It has the long drops, generally before 1977, BUT as this was a price point frame and build, they could always be using up old stock, the shift levers are also of the earlier type before the 80's. Those GS brake barrel adjusters are also from 1977 or so...
I am not ready to claim that is the year however. Note the 70th anniv. graphic, ending in 1979...
