I seem to recall attending a 'boot course(?)' at Cranners between OASC at Biggin Hill in August and IOT in November 1990. Same pair of boots throughout which yes, became muddy & scuffed and subsequently required bulling.
Not quite as frustrating as having to 'blanco' white, in order to acheive absolute uniformity, an otherwise perfectly acceptable pair of self-bought, as was permitted, trainers which had the temerity to feature a couple of darker stripes. "To the right with a jump, RIGHT!" Oh happy days
