Schick Krona Adjustable

With around five known examples, this is probably the rarest razor in my collection and I was extremely happy to snag it on an Ebay auction. Fortunately for me, it flew under everyones radar.
There are at least three patents on this razor, all filed in 1965, one granted in 1966/07 and the second in 1967/02 and the third in 1968/01, so at one point Schick must have considered competing in the DE adjustables market. This was a prototype that never got to market. Its obviously a Krona, but other than the Schick under the TTO knob, there are no manufacturers markings anywhere on the razor. This Schick logo was used around 1965-7.
The three patents are: US3293745, US3302284, US3363313. (Clicking on the numbers will open them in a new window)

The TTO knob doubles as the adjuster. In order to open the doors, you dial it past 9 and a spring mechanism pops the doors open. When the doors are open the numbers are covered. In order to close it, you pull the TTO knob down and rotate.

Its widely considered the best adjustable "never" made.

How does it shave?
Hey it's a Krona, and even on the highest settings, you need a sharp blade to get your BBS. They were made to be great every day shavers - This one is no different.
