@Powerlock Two I can think of - first, billed as defence of his title against Mike Marino, early 1970s in Kirkcaldy Ice Rink. Early 'small package' fall to Marino, quickly followed next round by an annoyed-looking Robin's basic pin fall after inflicting two thunderous body slams, then couple of entertaining fast skillful rounds with no playing to the gallery or boring lengthy holds/rests, winning pin fall securing all the opponent's limbs to Robin. Second, late 60s by DQ against Shozo Kobayashi in Empire Theatre, Inverness after he threw Robin over the top rope (second round?), so he landed very noisily in the orchestra pit. Robin quickly came bouncing back, throwing himself at Kobayashi to resume the bout, but Brian Crabtree had already issued the DQ. He may have initially thought Robin must surely have been injured, given the height and racket when he landed, but Crabtree refused to reverse the decision, much to the fury of the short-changed audience, who could see there was nothing technically wrong with the throw itself and both men looked ready and willing to resume within the space of a 10-count. But I do agree that a powerlock would have been the most likely outcome to satisfy the fans.
Andy Robin?
