This was used in the 74 / 75 League cup. No pictures unfortunately but your dad may recall Dennis McQuade scoring a superb goal against Clyde in the sections, Great run and goal with or without the offside rule. . Thistle won the group and drew Airdrie in the quarter final.
The league had started by then ( with normal offside rules) and by the time the quarter final was played, the Jags had completely forgotten the LC rules and Airdie hammered us 5-2 at Firhill. Good Airdie side though with Derek Mountfield, Paul Jonquin and Drew Busby.
