Unfortunately I don't have any leads on a modern equivalent.
(Just the fairly useless DEC part numbers.)

The construction is dead simple, though.  Essentially, mine are 
a set of reed switches mounted at 36 degree intervals, a couple 
of end plates, and a central shaft with a magnet on it.  Some 
detents which make the shaft tend to want to stay where you 
put it.  The newer ones presumably used an angle of 30 degrees 
instead of 36.

It's probably achievable to create something with a 3D printer 
and some modern reed switches that would fit the original form
