I've recently acquired a 30s Aristocrat in seemingly nice condition. When the razor is in the open position, with the silo doors open, I can freely open and close the doors just by pushing up and down on the TTO knob at the bottom of the handle, thereby sliding the rod in and out. They just flap open and shut. I can not do this with any of my Superspeeds or Slim. Turning the knob opens and closes the silo doors as it does on all of my other TTO razors. With or without blade in place they close evenly and securely.
Is this normal, by design, or is there something broken or missing internally?
Any knowledge, information or help is greatly appreciated. Thanks.
