Gillette "Red Dot" FatBoy

The Red Dot FatBoy is pretty much a Toggle with the FatBoy twist to open knob.
This one is a D1 so made in 1958. The adjustment dial is 1 - 9 and the same as the FatBoys. The indicator is the Red Dot and is obviously how the nickname was derived.
The adjuster plate is notched.

How does it shave?
I found it slightly more aggressive than a normal FatBoy
