Double seal corkscrew

A very interesting corkscrew turned up a few weeks ago at an auction house in the UK. A one of a kind Dutch silver double seal corkscrew. I don't recall ever seeing anything like it. But with any valuable corkscrew, its always a good idea to get a picture of the helix before bidding. I asked a week prior to the auction for a picture and got a response that they had added a picture to the catalog. A day before the auction, I ask again for a picture and they send me one showing that there is virtually nothing left of the helix, a very unfortunate revelation. With this in mind, I opted not to bid, but was somewhat surprised to see that it sold for so much. Hopefully, the buyer was aware of the condition. Nonetheless, it's still a very interesting corkscrew and would at least display well.
