My son-in-law found this in a thrift store today. It is a 1941 Gillette Ranger Tech. Gillette only made them in 1941 and 1946. (Break due to World War II). The 1941 has no end caps and writing on the band near the tip. The 1946 had end caps and no writing on the band.

Gillette only produced this razor for 6 months in 1941.

I will shave with it tomorrow.
