It's for inflating those dummy tanks and lorries we tricked the Germans with during the war ?
Might be current then. I came across a bunch of inflatable tanks while driving on a remote road in N. Scotland a few years ago. Round the corner, on the other side of a small hill, was a portable Rapier battery with crew. Shortly afterwards a pair of Harriers roared over. (RAF not feathered but I was happy 'cos I'd just seen a pair on Black Throated Divers).
