So, I just took some pictures I thought I would share with you guys. This is a matte finish Nickel Adjuster 1-5 Position Bottom Dial which was the true prototype for the regular 1-9 Bottom Dial. This prototype has an aluminum handle and aluminum TTO knob. The dial is nickel plated brass as are the working components like the silo doors and base plate. There is no date code but this was probably made in 1956 or 1957 (but I'm just guessing based on the patent filed for date.) This razor weighs 72 grams. The deal is this; a small number of these were made to test out how well this type of razor performed as part of the Gillette Research and Development test lab. I hear from another owner, who has been to the Procter & Gamble's Gillette Archives that, different prototypes of this razor had different weights so that the feel in a user's hands could also be gauged. This razor was never released for sale so there is no case, instructions, warranty card, blade pack, price tag or whatever. What you see is what you get: a razor only. This distinguishes this razor and it's cousin the Black Adjuster 1-5 Position Bottom Dial from all other Gillette Adjustable razors. That is, these are the only things that can truly be called prototypes. Not Red Dot Fatboys or 1-5 Position Serial Toggles.
