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.
