Question about model 694B speaker phone

[Southernphoneman]

I have just acquired a western electric model 694B speaker phone. What model telephone would this go in, could it go in a model 502? and if so what would the connections be? thank you.

It is part of a 2A intercommunicating system but you could probably interface it with most any telephone if you wish.  You can find additional info in the TCI Library by searching for 694 Subset.
