I've 'accidentally' collected just about every safety razor model Gillette has produced since commencing operations in 1904. Am shaving all week this week with the very first model, the 'Double-Ring' of 1904-1906.
Here's a latest find, a scarce Gillette Regent Tech (center), produced for only a short time before the advent of the U. S. involvement in World War II. Seen with the also uncommonly found Gillette Executive (left) which was rhodium plated and only produced in 1949, and the Aristocrat (center), the very first twist-to-open model Gillette, introduced to the market in 1934 and produced until 1940.
The Aristocrat with its open-comb design is my favorite of all Gillette models for shaving use as it gives a better shave than the later twist-to-open models as well as the earlier models. Makes one feel like Gary Cooper, Clark Gable, or Humphrey Bogart to shave with it.
The Regent Tech in its case.
