This was put together by a guy who repairs Gillettes in Hungary.
Its actually a mixture of various razors, but the underlying theme is a FatBoy mated to a FlairTip.
It works pretty much like a Gillette Adjustable except for the fact that once the doors are closed, you are unable to adjust the gap - so in order to adjust the gap on the fly its: Open doors slightly => Adjjust Gap => Close Doors again.
I think that most Gillette Adjustable user already do this anyway but if not once you are used to it, its pretty easy.
