Field guide needed: Gillette adjustables

I'm looking for an adjustable, preferably a fatboy. The trouble is that, especially in crummy photos, it is hard for me to tell if the razor in question is a fatboy or a slim. And, what does a Super Adjustable look like, a Slim with a black handle?

I'm looking in the "back corners" of the 'bay and shops and estate sales. Any help in ID-ing my quarry would be appreciated.
