The stores of the South London CCF Battalion I ended up as RQMS of in the late 60s included a boxful of WWI uniforms we shipped off to Richard Attenborough for the filming of Oh What a Lovely War... that's how little idea my predecessors had of what was in there.

Wasn't just foodstuffs though -
Pots - black as lava rocks
Forms - buzzing round in swarms
Spats - stank like alley cats
Boots - underneath(?) the roots
come to mind - but it was forty years ago!
