What's this razor?

[markh58]

My Son in Law fetched out of his barn a near mint Gillette black handle TTO.
It looks like my Slim Handle Fat Boy (?).
Date code T-4

Any guidance appreciated

1973 black handle super speed if the endknob is silver and just the handle is black
if it is adjustable than you have a super adjustable

sounds like a short handle Super-Adjustable from the last quarter of 1973

Thxs for the feedback, the handle and TTO mechanism are black and has 1-9 adjustments.
