This suit picture is exact to the suit sold a few years ago by PIH (it has the same cracked crotch, and the exact same catalog wording)
Here is the current listing from PIH:
COMPLETE STORMTROOPER TOUR COSTUME FROM STAR WARS: EPISODE IV - A NEW HOPE. - (TCF, 1977) This set of Stormtrooper armor was commissioned by Twentieth Century-Fox for the 1997 theatrical re-release of the Star Wars Special Edition feature film in Europe. This complete set of armor is one of only thirty made for the promotion, and was made by Offworld Effects at Elstree Studios, London. Extremely accurate, it was cast from an original Stormtrooper costume used in the Star Wars lms. By the end of the tour only fifteen of the original thirty sets of armor survived. These costumes formed part of the display at the Royal Charity Performance of Star Wars in London, England. Small
crack in the groin area (visible in the catalog image), otherwise in good condition overall. Also accompanied with a resin Stormtrooper blaster. Special shipping arrangements apply.
