Before I start we need to establish if black handle Type E razors are their own subset of razors or not. If we go by this advertisement then the answer is clear. They aren't. Magazine Repeater Company sold the black and gold along with the onyx-composition and gold razors as different styles of the same razor.
Now on to the pictures, First picture has 8 of the 9 styles sold in the order they were made, the last shows the first style of black handle Type E razor.
Here is a Deluxe set of depending how you want define it as either a 1st variant using this dummies guide or an E5v1 or black handled E1. Notice the box says black handle also.
From left to right:

Column ①, first variants, distinguishing feature is the square spring, missing is the black handle version in the picture. It is featured in it's own separate picture.
Column ②, second variants, distinguishing feature is the change of the style of spring from squared to round. Came in two handle styles.

Column ④, fourth variant, distinguishing feature is the extra tab on the left to hold the spring in place.
Column ⑤, fifth variant, distinguishing feature is the redesign of the spring, tab is now centered to lock the spring in place.
Column ⑥, sixth variant, distinguishing feature is the addition of striations on the guard to help stretch skin better.

Canadian E3 or 6th variant
Common accepted view is Type E razors were stopped being produced around the end of 1945 coinciding with the end of WWII and Magazine Repeating Razor company selling the brand to Eversharp.
That is partially true, for American made injectors they did stop production and didn't resume again until around May/June of 1946 with the introduction of the Type G injectors and first models branded as Eversharp on retail level in June of 46. In Canada that is not the case. The Type Gs were also rolled out in June of 46 but they had restarted production of the Canadian made Type E razors specifically the Canadian Type E3 or 6th variant in March or April of 46 and were selling them retail in April of 46 and at least until 1947. The Canadian Type E razors we also know for sure were produced in 46 or later regardless of advert pictures by the springs being branded Eversharp Schick.
We also know now that unique Canadian Type E that has a black handle and/or blue and chrome head made post war between 1946-47 is not a one off but a cheaper variant of the Type E3 which also came in the standard onyx colored handle with gold plated razor head as can be seen here.
Standard Canadian Type E3 or 6th variant 46 - 47:
Unique i.e. black, possibly blue handle Canadian Type E3 or 6th variant 46-47:
So to summarize American made Type E razors were produced from 1935-1945 and Canadian Type E razors from 193x-1947. Type G and Canadian Type E razors were produced concurrently during at least part of 1946 from June onwards until the Canadian Type E razors were discontinued.
