I have a box of Blue blades and trying to figure out what year they are from. Marked 'E2', looked on Mr-Razor but didn't see that code. Any ideas?
Forgot to add that date codes started over at A1 in 1955. There is a possibility they are second quarter 1959. I'm not sure if they came wrapped in paper in the cardboard box in 59.
They may have been in the sold in the metal and plastic dispenser.
