Oh yes. I've been using all of them. Nothing but vintage Gillettes for the last month solid. Well, I haven't used the little travel Tech. When I got it, I was pretty surprised at the condition is was in.... I don't think it's ever been used. Not that that is why I haven't used it.... I just have been busy using everything else. I'd say about half of them came in their original cases and the other half I pieced together. It's been fun learning all of the little variations in the Super Speeds and adjustables over the years. It's kept me busy.
Ebay. The Fatboy came with its case but no blades or instructions. As to be expected, it was the most expensive of the lot. I still have to find the correct blades to go with that one.... but I've picked up a couple of lots of NOS Gillette blades with dispensers from roughly the era of the razors. A few of the razors came with the original blade dispensers and instructions.... like the Slim, the '58 TV Special Super Speed, and the '59 Regular Super Speed Flare Tip. The '59 blades and instructions are still wrapped in cellophane. I'm not too bent on having them all perfect and accurate. I like to use them, they are not for display exactly.
