That spacesuit looks familiar .....

Whenever you watch THE EMPIRE STRIKES BACK , do you get the feeling that you've seen bounty hunter Bossk's costume before?

Well, you have, (if you're an uber nerd). It was recycled from a spacesuit seen on a 1966 episode of DR WHO.

first used in the 1964 film FIRST MEN IN THE MOON perhaps?

and Dr Who, 1968


Update: I've recently learned that it is  a Windak high altitude pressure suit, developed for the RAF in 1962. The suit was constructed from a single layer of gas tight rubberised silk bonded to strong cotton. It was internally pressurised by air in order to achieve a higher pressure upon the wearer's body than naturally occurs at very high altitudes and beyond.
