The Sangamo Electric Co <http://sangamoncountyhistory.org/wp/?p=1410> . manufactured  electrical meters, time switches and sonar and radio equipment, among other items, in Springfield, IL from the 1890s until 1978.

If your US house is old enough u might still have one of their meters on the wall


The device is either an instrumentation or an audio recorder, see: https://americanhistory.si.edu/collections/search/object/SILNMAHTL_16729

I put up some more pics (Tapehead & capstan drive). It does not use stepper.


It seems it was made by US firm Sangamo, as is etched in some of the PCB's


In view of the head's condition I will not persue this further.
