Bargain!
$15 got me a No.15 Set box and case. Alas, it did not contain the period correct razor. The best I can make out the razor in this mismatched purchase is a No.66 1958 Aristocrat, matching this one.

Inside the case also was an old Canada head & plate open comb in reasonable condition. No handle however. Looks like I'll just have to make a stainless one for it.
The Aristocrat razor is in very nice condition. Small plating loss underside of the doors in opposite corners at one end, but otherwise, it's a very nice razor. Shaved this morning with it. Not an aggressive shaver by any means, but it does shave, nicely too. I do like the Aristocrat range. They just seem special. Think I'll try a very gentle polish around the head to brighten up the rhodium a little. Looks a little dull at the moment.
So I have a good No.66 razor, without it's case.
The box is in bad condition, but you can somewhat see and read everything, historical interest maybe. Underneath the box you can see the date 9-6-41 written in pencil. The booklet inside the case lid looks like it's never been removed. Prying up the edges to get it out looked like it might lead to harming the paper, so I left it there, for now. Hoping the Gillette logo behind it is mint?? It's far from "new in box" being 80 years old now, but it was very cheap.
The seller also had a toasty old Rolls in box, and an old Valet single edge in box (the one with the 2 little gears on side of the head), complete with rusted blade in place, ruining the interior and comb teeth, just making a horrible mess of itself. I left those with him. While being old survivors, condition was terrible, and neither were for using. Put away wet and forgotten about. Decided I don't need to buy everything I see when I see it. But I did want the Aristocrat for $15 though!
