So, on special request here are some pictures of the Schick M3 injector aka the protector. It's called that way because it has button that moves the guard bar up to the blade in a way that the blade cannot harm other things (or beings), and vice versa in a way that other things cannot harm the blade. Nice when you're on the road.
Let's start with a family picture of the M injectors I have. There's also a prototype, but that baby is very very rare.
Left to right: M1 dial, M2 adjustable, M3 protector

Turned around, you can see the slide button of the M3 (a little out of focus...)

Now for the M3. In this picture the the slide button is down, the razor ready to rock and roll, the blade gap is obvious.
