WTF is this...."M20 alpina content"

The throttle linkage looks to have some kind of vaccuum regulator attatched to it, what is it?

thats the old school idle control valve from the pre- motronic cars---- aka e21/ e30 non-cat 320/e30 323i cars.
when the vacuum would drop, the stud would come out of the vacuum piece and raise the throttle.--
