Lear ADF-12 Orienter

[Crimea_River]

A long shot but is anyone here familiar with the subject ADF system used in the 1950's? I am researching equipment needed for our Spartan Mosquito restoration. I have model numbers of the Lear equipment but get no hits on the web or through Chat GPT. It would help if I could determine what Lear ADF system they fall under (12B, C, or D or other?) and then to get a manual or system diagram.

This is the equipment in question:

Never mind. Discovered the system is ADF-14 and bought the manual on EBay just now.
