Who’ll tell which phone is what?

Today I received my North Electric Brown phone. A real one this time, after the interesting but slightly disappointing CEAC model (see post of December 2014).

Here are the 3 brown Ericofons in a row. There is a slight color difference between the CEAC and the NE. The PTT brown can clearly be recognized.

The inside of the North Electric shell does not reveal any information on the production date. The chassis is from ’59 and the microphone from ’63. Does not say anything but if it is an original set, it was also compiled out of spare parts.
