Aye, you're on right on the Button Bob....My collection of injectors includes a couple of Schick E3's which are among my favorites. I've wanted one of the earlier models for some time and recently acquired one. This is an early E2 with a smooth guard and a crinkle finish.

This has the type of spring that allows for opening up the razor.

Here is probably the most important picture of this post, the E2 on the left and an E3 on the right:

If you have a razor with the type of spring on the right, with the notch in the center of the top of the spring, do not attempt to open up the razor. You will likely damage the spring and possibly render the razor unusable. LIkewise, when shopping on the 'bay be wary of razors with the spring on the right on which you can see a scratch indicating that the razor has been opened.
The big surprise came when I loaded up a blade and shaved with the E2. As previously mentioned, the E3 is one of my favorites, having a near-ideal (to me) balance between aggressiveness and smoothness.
Whoa - the E2 is much, much more aggressive, right up there with a MMOC, Ever-Ready 1924 or an Auto-Strop VB1. It had me reaching for the magnifying glass to make certain that the blade was properly seated under the blade stops (it was). I enjoy aggressive razors (my go-to razor is an Ever-Ready 1924), but this one demands a lot of respect.
So, why the big difference between the E2 and E3? At a glance they appear almost identical.

Looking closely, it can be seen that there is a big difference in the geometry of the relationship of the guard to the blade. The E3 (on the right) has the guard extending out in front of the blade, while the guard on the E2 is nearly flush with the blade, more like a MMOC or a lather catcher. The grooves on the guard of the E3 might also be a factor.
When I got my first E3 I felt that all the talk regarding the aggressiveness of the E's was overblown. Now I get it - I just didn't have the right E.
Yeah, all the Type E 2s are a Smooth Comb Design....The grooved Comb came into being with the later Type E 3 and the Type E 4 had the Grooves also but can be identified as having the side lugs removed from the spring like the later G Types....I think I have an E2, and here I was all along thinking it was an E3. I thought my "grooves" made it an E3, bu closer inspection says "light scratching" not grooves at all.
