Make no mistake that 2nd suit is significantly better that this - not least as it had the ANH/ESB helmet.
Personally-speaking I'm a little surprised it topped the £200k mark but as Mic has said, you only need 2 people in the room that REALLY want it (oh and have the funds to match :lol)
However I was pretty convinced that it was probably THE only ESB Mk2 suit that was used in the movie. It seems clear that most of the leftovers from ANH were adequate for ESB shooting, except for a few final Bespin scenes where additional parts were required. As per my preview of this, it seemed clear to me that this was a suit made from leftover ANH parts and newly vac-formed (ESB Mk2) parts that John Mollo's team had to hastily put together in time for filming. After the work I did a couple of years ago with Mr Mollo, plus some subsequent investigations - it seemed a very good bet that this was the real deal.
I'm pleased for the seller that it went for such a significant amount and am sure that the 2 bidders who drove it to that price were absolutely clear on what they were doing. I didnt have that final bit of photographic proof that would have made it 100%, but maybe they did
As far as Christies estimate, I think following the problems last year with the Vader suit they really wanted to make sure they did this sale exactly by the book. So I was pleased that they contacted me and we were able to ensure this suit was presented as accurately as possible, while also generating some good publicity for the auction. It looks like it was pretty successful process.
Cheers
