Smart Vulcan groundcrew? You've gotta be joking!
Standard winter uniform for Vulcan Line Maintenance personnel was scuffed "Troglodite" boots, sea boot socks rolled down over the boot tops, battledress trousers tucked into the sea boot socks, RAF issue shirt with your own choice of jersey, in cold weather add a cast-off aircrew beaver-tail parka liberally patched with black bodge tape and the tail hanging down in the trail, a woolly balaclava (usually knitted by your Grandma) finished off with a football scarf in the colours of your chosen team.
SNCOs wore the standard Technical Branch SNCO's uniform of battledress, brown dustcoat and "fly-away" beret with the surplus adjusting tape hanging out of the back. When working outside, add Trog boots a cast-off beaver tail parka and a well thumbed dog-eared copy of the Vol One. One was led to believe that a true blue time-served Chiefy was required to wear his brown dustcoat over his pyjamas at night. Crew Chiefs slept with their aircraft. Naturally.
