Does anybody know if there is a Written specification for the
Temperature Compensation found on the early Model 7's ?

I have found the following after testing the one on my 1946 Vintage
Model 7.

The temperature Compensator was measured as 2.5 Ohms and this is in
addition to and in series with the Swamp and Movement.

The Compensator seems to have a Range of around 22 Degrees C.
I tested mine from 3.5 Deg C up to 26 Deg C.
3.5 deg C equates to the full 2.5 Ohms.
26 deg C equates to Zero Ohms.

So the question really is, at what point should the Compensator be set?

At what Temperature is it supposed to start reducing it's resistance from maximum and
at what Temperature should it reach Zero Ohms?
