Might as well add a few not well known sets to this, both are Canadian Rockets as documented here. These razors are unique from Super Speeds or Milords in that they lack any made in USA stamps or US patent info on the razors. https://theshaveden.com/forums/threads/gillette-canadian-rocket-tto-timeline.62771/ This one was sold from 1950 - 1954. This one is called a Deluxe Rocket set and was sold from 1952 - 1956.
