THANK YOU! I'll post a photo of this call box when I get a chance. It is a pretty interesting device. The top part has a coded telegraph unit (pull for fire) and the bottom half has a telephone. There were two versions - one had the telephone for public access and the other had a locked door so that the telephone was only available for use by police and emergency personnel. Here's some information from the patent: https://www.freepatentsonline.com/3009023.pdf
