Interesting to hear that Montague Burton made No.1 uniforms for re-labelling by more expensive tailors. No.1s direct from Burton were common amongst officer students at Cranwell in the late 60s, but it helped to order one from a nearby branch than from a Burtons in one's home town. One of my students tried that, at a time when faux military uniforms were all the rage in Carnaby Street and its surrounds, and said "I'd like to order an RAF officer's No.1 uniform, please". To which the Burton salesman replied "Certainly, Sir. What colour would you like it?"
