Mystery turn control device on older jets

I recall seeing, long ago, a sort of large knob on the pedestal of a jet (I
can't remember which kind) that, when turned, put the aircraft into a
coordinated turn ... at least if I recall correctly. No modern jets seem to
have anything like this. Am I imagining things, or did something like this
exist on earlier jets. I recall it being called a flight director, I think,
but the behavior doesn't seem to be like the devices people call flight
directors today.

Well not remembering which jet leaves the field wide open...but if it
was on the pedestal of a B737 200 series or a B727 or a B707 you were
looking at the rudder trim knob.
