56E PX/4 [?] Bell.
I recently got this bell in a job lot of telephone equipment and was wondering if anybody has any information on it?
The only thing that could be a model number is "56E PX/4" stamped in white on the back. Each coil has a resistance of 2.2kΩ. The two resistors which can be seen on the rear view are 270Ω and 2.2kΩ. - Joe |

That looks like a DC operated trembler bell of some sort, though it might function on the usual AC ringing signal. Maybe from some internal phone system?

I wondered that but it looks like a Post Office, or other government thing, and the capacitor seemed a strange thing to include if it wasn't for a 'phone of some type.
Thanks - Joe |
