'Twas in mid-60s, we much admired the USAF name tags, pin fastened with a clutch and white lettering carved in fetching blue. We git 'orrible white badges, safety pin and dump tape.
Next someone sourced a bit better one, white plastic with black lettering, but design and wearing was very much a station thing. Anyway we really didn't need a name tag on working dress as we all had security tags.
Anyway, Bomber Command decided uniform tags were a 'good idea' (promote that man) and bought their own machine. It was decreed all officers would wear a standard blue and white WITH clutch pins. Officers were billed through mess bills IIRC. They were met with universal acclaim
. They were a darker blue than the later version.
