Hi Mike! Yes, I do ...
I have concentrated that collection on the 1912 (of which I have over 60, all which I can point specific details unique to each) plus what I think is one of every variant of the 1914, a couple of 1924s (one with the cap engrved with thanks from Sears & Roebuck whose catalogue practically launched that line of razors and a brass one). I have 5 or 6 various Streamlines, still missing a Gem Streamline though. Then there's the Damaskeenes (about 10 of them), just two Feathweight/Natural Angle (one olive handle, the other a gold Deluxe) a large handful of lather catchers and pre-Damaskeenes, and of course my mint Sun Ray, my shaver Sun Ray and I got another Sun Ray in a single case. I rather prize them higher than the Streamlines 8)
Oh, and I re-bought the Contours after selling them in with a job lot < they're kinda 1912s, in a way ...
I sold off all the post-1919 style razors to a collector in Germany who therefore got an instant and pretty wide collection of Micromatics, Featherweights, Natural Angle/Flying Wing, Pushbutton & Contour. He wasn't much of a fan of the 1912 and collected the rest, so that worked out really well for us both.
Yeah, one or two other interesting ones ...
I was just looking at the Wilkinson Sword Patent Roller Safety Shaver (1901, was it?) which was licensed to Henckels. I've got a pre-Valet Autostrop 7 O'Clock, a Le Grelot, a L'Essor; the list goes on. More in the loft.
Truth be told, I've always had a good collection of Gillette Tech and New razors. I've always enjoyed them simply as objects, and that I can also shave with them was a bonus. I sold off a lot of the periphery, concentrating on pretty much the Tech but also British New. Good to bolster that collection a little. I'm enjoying double edge again, returning to traditional shaving after a little break of tardiness, beard-growing and Gillette Dyson shaving.
I'll be showing 1912s again in SOTD before long ...
EDIT: I did try to photograph them once - this was by no means the whole collection but a damn good part of it.
