Oscillator Module Switch Wafers

The oscillator module has three wafers: 8, 9 and 10 counting from the rear of the radio.
On the schematic, these switches are labeled SW8-11, SW8-12/13, SW8-14 and SW8-15 respectively.
On the very earliest radios, SW8-15 is not used.

Beware of different viewpoints. One is 'through', the other is face on.

The SW8-13 pin that is shown connecting to C69 is, according to the schematic, also supposed to connect to C13 (to ground) and SW8-12.
Need to figure out how that works.
