The Tech came in. It turns out it is a common right-handed tech. The base of the case had been turned around. I fixed it. I will use the case for my Gillette New Standard. In the tuck was a Gillette Blue Blade z4 and three Star blades. My New Standard looks pretty good in it.
It was not advertised as left-handed. That was my take. Just having fun. I got it mostly for the case. The tech was just a plus. I flipped the base around. It will make a nice home for my New Standard.
The Star blades were a bonus, too. From the address on the back, it puts them pre-Zip Code era (1963).
