The 49 set was sold at $5 or $2.50 depending the retailer. G4 sold 1948 - 1951 sold as the Schick 66 G8 sold 1954 - 1957 first ribbed handle razor predating the I2 hydro magic by a few months in 1954. No info found on the other known variants. First the G1 which came in 3 variants. G1v1 was produced in 1946 and 1947 and is differentiated by the what is written on the injector spring. These models have the older Schick Injector marking on the spring like the earlier models. G1v2 and G1v3 are differentiated by ferrules on the handles, both have the newer Eversharp Schick markings on the spring, G1v2 has the square like ferrule and the G1v3 has a rounded ferrule which you also see the G8 razors which superseded the G1 in 1954. Here are pictures of the 3 variants G1v1 1946 - 1947 G1v1 Pictured on the right is the G1v3 1953 - 1954 and on the left G1v2 1948 - 1952 G1v2—G1v3 There are also some Canadian made Type G razors that are unique in that they are black handle variants. They were definitely made 1946 or later because both have the Eversharp name on the springs. One came with the old style Type spring with the side tabs and the other with the standard Type G injectors. Here is one with the older Type E style spring, it is also possible the handle is blue and not black but either way that spring is what makes it unique. Here is one with the newer spring style and black handle. G4 aka the Schick 66 came in 2 styles gold and chrome plated heads.

The I and J were the same razors with 1 or 2 exceptions with different handle styles as per Schick the I handles would be the classic handle and J handle the long handle when sold concurrently. To understand the revisions you need to know that Schick changed the logo on the razor stamps 3 times during this time period. First was 1954 with the introduction of the hydro magic razors, they were stamped Eversharp hydro magic for the I2. In 1959 Eversharp is dropped from the logo and the stamps are changed to Schick Safety Razors on the I1. Finally in 1964 the logo on the I1 is changed to Schick. For more detailed analysis on the differences and v1/2/3 etc nomenclature see here. I2 1954 - 1961 Iv1 1957 - 1959 Iv2 1959 - 1964 Iv3 1964 - 1967 The I2 hydro-magics came in 2 major variants regardless of gold or chrome heads. It is unclear when the transition occurred from one style to the other. The earlier variants have a hydro-magic lever that looks like this. These were produced between 1954 - 1958. The later variants the lever looks like this and were produced between 1958 - 1961. First instance of the the I2 Ad from the Progress Index Apr. 29th 1954 Progress Index Click for full page With this particular razor we can date the switch over on the levers to 1958 What makes it unique is the logo change and set name change to Eversharp Schick this only happened with this razor for a few months in 1958 as seen here. Ad from the Arizona Republic Mar. 27th 1958 Arizona Republic Click for full page By Christmas of 1958 it is back to Eversharp Hydro-magic and all new injector which can only refer to one thing. They changed the razor. We know the longer and shorter lever hydro-magics do not shave the same so this is what they are referring to as new. Same style different shaver and lever and switch over date confirmed.
