I have just purchased another razor from E Bay UK ( Okay I'm hooked I admit it) It's a British flare tip rocket but unlike the other British Flare tip that I own, the handle above the flare tip has a ring free of knurling. Unlike my other flare tip the the adjustment knob does not move up and down when the doors of the razor are opened or closed . It also seems pretty shiny compared to the zinc plated example that I also own. The bottom of the head is stamped with the Gillette triangle and Made in England and the inside is stamped Brit Pat 594093. Any thoughts on this razor would be greatly appreciated.
