Found today! Gillette Super Speed Blue Tip A-2 in great condition! Purchase price? One stinkin' dollar! Woot!
I got a blue tip at a flea market for $3. It was full of soap scum but really cleaned up nice. No loss of plating at all. Once I polished it, it looked brand new. They are great razors!!
I got my first Fat Boy from the bay for 70 delivered, found my second cased for 55 in the wild and got my third for 10 in the wild. No case on the 10 one.
I only need 1, so I was patient on the bay till I found one reasonably priced and got lucky. When you run into them in the wild, they are crying for a home so you just have to purchase them and bring them home.
