I just got this mint Tech razor. The razor has date code of L3 so I believe that would make it produced in 1966. It does not appear to have been ever used. The razor came with the original blade, unused, in the razor. When I bought the razor online I saw that it was in great condition but did not expect it to be NOS. The box indicates Gillette in Boston, MA, and the blade says it is Super Stainless.
