Manufacturer of the Tachometer

[WDM#326]

Has anyone been able to determine who the manufacturer for the tachometer is? Mine has unfortunately passed on. The hour meter is still working, so it will stay for a while longer. I have done all the trouble shooting steps I found in other postings and the Telex website. I even confirmed the signal was making it to the instrument by using jumpers and another tachometer I had in the garage.

In a past life I used to repair aviation instruments, so I figured if I could find some information on the manufacturer I'd be able to trace down some specs and take a look at the guts myself (Looking for a winter project
