Capacitor for coin chute electromagnet

[James]

Does anyone know if there is a source for purchasing a Western/Northern Electric 452 or 452b capacitor or if anyone might know what the capacitance value is? My payphone is missing this part. The coin chute is a P20A119 with the P349754 gong assembly.

Update:

I found the answer to my question about the capacitance value, in case anyone wants or needs to know.

It's  4mF (microfarads) and its purpose is to "minimize voice transmission loss and unbalance to ground."

I got the information from this pdf file: http://www.telephonecollectors.info/index.php?option=com_docman&task=doc_details&gid=4765&Itemid=2
