My wifes uncle gave me a couple old razors that belonged to his Dad. Can any help me figure out how old they are? One is a Gillette Adjustable with a baby blue and clear plastic box. On the back of the razor there is a K and a 1. It has a short silver knurled handle. The other razor is a Gilette Tech and has a fluted black plastic handle, The blades that came with it say on the box Gilette blue blades. On the back there is a W and a 1. I have included pictures of both razors.
Slim and a tech. K1 is 1st quarter 1965. W1 is first quarter 1961. I believe these are correct. http://www.geocities.com/safetyrazors/gil_ser2.htm
