Ralph, as I mentioned in the above post, there was a switch to select intercom, but I also remember some buttons on this same box. It seems like there was a printed label next to them - probably the location of the extensions. I suppose to call a certain station in the house, you set the switch to intercom, then pushed that button to ring or buzz that phone. I'm guessing it worked like the manual intercom used on 1a2 systems. I didn't see any other old phones in this house, as the working ones were all standard modern sets. I wish I could remember more, but it's been over 50 years since I was in that house. The house was built sometime between 1900-1915, but the old phone system was likely from the late 20's - mid 30's.
The phone in the hall looked a lot like the one in the link.[this post was last edited: 1/15/2019-18:22]
