Here is one, recently closed, that I thought was strange; For a Gillette Tech it does look nice, but I seen these come up and sell, new in the box for cheaper. Not to bad mind you, but if you look at the bidding there is some odd activity there as well... https://www.ebay.com/itm/223197255641
I found it interesting that the only bidder with 3-digit feedback bailed at about what it should be worth. Either something odd was up or someone with no experience of actual value got it in their head that they had to have a post-war Tech and it had to be pristine looking.
