MACO Space Suit
This suit was originally made for the motion picture "The Core" and later rented by the Enterprise Costume Department. Sadly the costume hasn't aged well and jumpsuit and the back pack have had considerable deterioration. Shoes, gloves etc. look fine. It still displays very well, there's no problem to the thick jumpsuit itself, just the outer layer.
If interested, contact me and I will pass it on to the seller, a well known Star Trek Prop, Costume & Auction member. He is asking $ 3,000.
