who does VOR "calibration" for most accurate VOR approaches?

Most VOR receivers/heads have a fairly accessable calibration control for

our radio shop's owner to another week in Hawaii know how to find those
controls.

Easier said than done. The screw drivers that do that adjustment are
highly unique and seemingly impossible to find. My shop got theirs back
in the 50's. I spent about a month calling every place I could think of
to get the proper driver to adjust a basic King head and never got
anywhere. I think you need to wait around a shop until the old guy dies
and then grab his.

Do you know what the name of the type of driver this is? I thought it
was just a spline driver but my shop said it wasn't. They were not sure
what it was called by they call it a "Cessna avionics driver" (even
though this is just a basic King head). They said if you tried to use a
regular spline driver it would probably strip the screws. Looking at
their driver it was the strangest shapped head I've ever seen.

So far as I know it is the smallest spline driver you can buy. At least
that's what I've been using for a goodly number of years.
