This is my 1950's Super Speed, I've been restoring this and the single edged GEM I bought last weekend. According to the Gillette razor identifying wiki SS razors post 1950 had the mark PAT NOS ON PKG, this one also as no date code so I'm assuming its somewhere between 1950-1954. All I need now is some metal polish, there is a strange yellow rust like residue on the bottom even after multiple passes of scrubbing bubbles. The orange rush on the inside of the head went away thankfully.
Any idea what the yellow stuff could be on the bottom of the head? I'll take more photos.
