Scottish National Hunt jockey Robert Docherty was associated with James Craig Brown’s Linlithgow stable. He rode just one winner, when 7-1 chance Bonnytoun made practically all the running to land the Streetlam Novices’ Hurdle (Division 2) at Catterick Bridge on Saturday, November 2, 1963, drawing clear on the run-on to beat 33-1 outsider Solon Bay, trained and ridden by Barney Cross, by four lengths, with another 33-1 chance, Red Hat, the mount of Nimrod Wilkinson, half a length further back in third.
