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:

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.

The head doesn't look to be large enough to hold read and write
components (regular 1/2" computer tape drives usually have a
read-after-write setup).

My guess is a data logger or key-to-tape setup.

That would fit right in with a key-tape scheme.   Can you tell if the
capstan motor is a stepper?

Anyone recognizes this ? The paddle PCB says "paddle 
board, 7/9 level tape handler."


Not even sure if it is a computer tape drive or an 
instrument  / data logger...



I'm pretty sure it is a digital/computer drive.  It really 
looks military to me.  Possibly from some test gear.

have never seen anything like it, but given the labels are in english
but there are european electrolytics, I'm guessing it was made in the UK

What's the date on the paddle board?

Could almost be a key-to-tape drive.

1970, also all TTL is dated 1969 or 1970.
