Underground shedworking in a nuclear bunker

We've always been intrigued by the idea of shedworking underground here at Shedworking but never had much luck in tracking down examples. But here's a real possibility, currently up for sale on ebay (bidding ends March 7): a decommissioned nuclear bunker in the Peak District. The bunker, used as a Master Post, has great views over the Derbyshire Dales and was in use from 1959 until 1991.

It's on private land, fenced and gated 200 yards from a road. You get into it through a metal shaft and down a ladder which takes you into the two rooms (including chemical toilet), the large monitoring room measuring 15ft by 7ft 6in. Features include two ventilation shafts, BT telephone line, 12 volt battery lighting, desk, chair, enamel bucket, siren box and all sorts of associated goodies.
