The game was at Ibrox as stated by Alex venters, November 11th 1978, a 1-1 draw with Lynch scoring for them & Alex Forsyth netting a penalty for us. The Rangers Companion lists Alex Miller as number 11 that day, which is the only time he wore that number during the possible timeframe for the picture.
That game was at Hampden. We played both our home league games v them at Hampden that season as the Copland stand was being built.
