This Gillette is what many of us call the "Daddy" of the SS. Made in 1941 this type of twist to open didn't appear again until 1947. With refinements they called it a Super Speed. The Ranger Tech is a TTO razor that is well balanced and silver plated I believe. Gives a really close shave. The blade exposure to me seems a bit bolder than the SS's that we know. Mine is a little rough around the edges but a super shaver. If I ever find a better one that I can afford I will replace it because it's staying in my rotation.
