There's several editions of the Rolls Razor. I have one myself. The one in your pic, given the case, is probably the Silver Edition of the Imperial 2 Rolls Razor. Ones without the case were nickel.
And there's several other editions as mentioned. How you tell them apart is the exterior design on the metal case.
Personally, I like the Rolls. And there's some interesting facts about the company and the owner. The owner, even after the company folded took all the inventory he had of the Rolls and up till it ran out or he passed away (I can't remember which) he honored the warranty and you could buy blades and replacement parts from him. Just by writing to him in England somewhere. I heard great things about him online.
Not something you see from many, especially after the company folds.
You can get the blades rehoned true. A couple places do it and one offers new blades they themselves make for them. Practice on a balloon.. I did. Lol. A fresh open blade on that thing.. it'll make you nervous bringing it to you face the first time.
There's a video of a guy on YouTube of a guys first time with the Rolls and what he thought of the shave.. He liked it from what I remember. Felt it was as close as he was getting from other blades he tried. So..
I "saw" a very interesting 7 day set at the antique shop where i bought my Rolls. I've never seen another like it. I don't know who made it, maybe you do.
It was a complete valay(sp?) of wood, dark in color. It included the brush, cup and a rack which held 7 razors, each marked for the day of the week. The rack which was metal, and all the razors where gold plated. Or gold... I wasn't allowed to touch it but he did show it to me. Price tag was up there, I remember that. Way up there. He had it in its own display case right next to his desk.
The handles and razor rack where all scrolled and fancy. It sure was pretty... Like a Rolls, as far as the blades, but definitely not a Rolls.
Ever seen one like it?
