I have been looking at the schematics, and the pictures, and it looks like it may have been refurbed at one time, so the box with ringer and inductor may be older then the rest. It looks like it has been an older induction coil mounted on the back wall over the inductor, the connection plate on the left wall looks more modern. I asked a friend about the schematics, and he suggested this could be a Leich telephone, and not Kellogg.
Regarding the capacitor so is that an option in the schematics so it would be fine with, and without.

This does not make things simple, but absolutely interesting.
