    I have a Hammond Postal Telegraph wall clock that needs the motor and movement. I have attached some photos of the clock face and wall mount.

    The Hammond "Postal Telegraph" clock is constructed with a single unitized AC electric motor and the clock works all in one unit.

    It's not a simple AC electric clock. It has an inertia spring driven motor that attempts to keep the clock running and keeping time for a brief period during electrical outages.

    It is not a "simple" repair to investigate a non-functioning unit, locate the problem, repair or replace any worn parts (no new parts available) and re-assemble.

    Many available examples have been subjected to "best-effort-fix" by well meaning home craftsmen and rendered well beyond economic repair or restoration to function as originally designed. There is a weakness in the construction, a large fiber gear with fine teeth which if chipped or missing teeth is not replaceable. (end of life for the clock)

    Unless you can find a repairer who is prepared to undertake and investigate the cost to you will have to consider learning how to repair it yourself. Most repairers will not accept these older electric clocks for repair without a substantial cash deposit for analysis. Most will simply advise, "not worth repair" because of the amount of time and effort needed.

    I realize that my opinion is not what you want to hear. Others may advise differently.

    The Hammond Postal Clock had 2 movements: Bichronous and Synchronous. I can help you with this clock ONLY if you have your old movement. I need to know which movement your clock has. The clock will need to be cleaned, the coil is usually bad and the fiber turn to start wheel will be stripped. I need to know which movement you have before I can offer help or advice.
