All right this small guide is for all of those who wondered how to identify a Schick Injector Type E from a Type G on the B/S/Ts, antique shops, eBay, etc....
The injector Type E is usually regarded as the more aggressive shaver and from personal experience performs better than it's Type E cousin with heavy beards.
The injector Type G on the other hand is the perfect candidate for a Featherjector Frankenstein as it is the perfect aggressiveness to be coupled and to counter balance the really aggressive Feather blade. More on that in another guide to follow next week. The Type G is also very cheap to be had and is more readily found than the Type E.
All right, so if we look at both razors from the back one next to the other (bakelite), it is very hard to tell them apart:
Which one is which?
And if we look at front pictures, they would still look nearly identical:
So how to determine which one is which?
While there might several visual cue in reference to the handle colors that were limited to a specific model, but the easiest way to identify one from the other is to look closely at the razor's head.
On the type E, you will find a single patent number: 1806087
On the type G, you will find two patent numbers: 1806087 and 1969945.
These patents numbers are commonly mistaken for serial numbers or date codes. They are not.
Notice that the patent 1969945 is actually the patent for the blade loading mechanism which is the same on both, so I am speculating the reason the second patent number is not found on Type E's is because the patent was pending and not approved yet when the production of these razors started. If you look carefully on the Type E the texts says "others pending", probably referring to the blade loading mechanism patent.
Another common trait identifying the Type E from the Type G is a small seem running at the back of the handle. The Type E do not have any seem on the back of them, and the Type G's do have a vertical seem along the handle.
So here is what you should be looking for:
A single patent number
Two patents numbers
On a side note, here is a visual comparison on the aggressiveness of both types:
You can clearly see how much shorter is the blade to skin gap on the Type E (right) vs the Type G (left) thus making this razor more aggressive than it's descendant.
