I won this razor in the TSD raffle. It came today, and it cleaned up very well. Thanks, @Screwtape . This is the one that has Schick on both doors. The first pictures are right out of the box. ca. 1967-68: design revised for 1967 patents, plastic knob, one-ply center bar, often labelled with code 1-M, "PATENTS PENDING", doors stamped "Schick - Schick" or "Schick - Krona" or "Schick - (blank)", approximate weight 38-g. These pictures are after cleaning.
Great job with the clean up. Looks almost new. When you get the urge to shave with it, please give us your thoughts on how it shaves.
