Yes, I'm trying to work out the switching arrangements. (In order to determine which resistor goes where, and what their purpose is.) There appears to be a feed from the 'Speech' line as well, presumably to add the intercom audio to the loudspeaker output.
Has anyone got the circuit diagram of the loudspeaker? (I assume the terminals connect to different tappings on the matching transformer, or the WS19 terminals bypass the push button/capacitor arrangement used with the telephone system.)
More in a while....
