My dad recently found this razor in his basement and gave it to me. It looked horrible, so he nearly tossed it, but he knows that I like and use DE razors, so he fortunatly showed it to me first. A long dip in my ultrasonic cleaner got it looking like this. Only markings on the razor is "Gillette" on the lower left side of the handle and England on the lower right side. No visible markings under the trapdoors.
I have used it a few times and it shaves much like my Superspeed. Works just fine, but certainly nothing like my beloved Futur ;-)
