Hi Gizmo’s like that were very common in the days before network analyzers became good enough to measure a crystal. They always were a troublesome item to keep running accurately. Without accuracy, their value was a bit limited. Every place I know of had a big drawer ( or cabinet ) of “magic crystals”. You plugged them in and adjusted the instrument until they all read as they should. One could easily challenge this in terms of accuracy. It did ensure that all the meters in the plant had some chance of reading the outgoing product the same way.
So - you don’t just need the manual, you also need the batch of calibration crystals (and their data) that went with it. Then you can duplicate the readings from whatever factory used it …. Lots of fun !!!
