That was Jock Muir, who I think competed in many forms of motorcycle sport before the war, particularly sand racing from memory.He rode the MGP from 1930-33, eight races, winning the '31 Senior, and a 2nd, a 3rd a 5th, and the 13th mentioned above. Finishing in 5 out 8 races was a pretty fair achievement in those days. He didn't compete in the TT, but was certainly a prominent Scottish competitor, and I'm sure someone will have some knowledge of him. Over to Larry and Bill!
