1: (8)746 hookswitch - had to desolder it from a 1983 PCB and resolder it onto this 1972 one & realign the spring/metal bits - PO/BT changed the side the metal base of the switch lever is on over the years!
2: 4000R bell coils (also from 1983), with wiring changes for BT plug and socket make this an 8746 rather than just a 746 #telephone
Better than just putting a 3k3 resistor in series with a 1000R bell, that doesn't sound as loud with the lower ringing voltages often used today.
