I picked this up at the flea market yesterday.
If I'm reading the date code of M-4 correctly, this is a 1967 Gillette Knack.
After a little scrubbing w/ a toothbrush and some dishsoap and then a little baking soda, it cleaned up quite nicely. (Though there's still a little bit of gunk I couldn't clean off on the underside, so any suggestions on the best way to try and clean that would be appreciated.)
