Some things missing:
1. The reference drawing or location for the 120 volt power supply.
2. Descriptions of the CR0000 to CR0002 interposing relays on lines 302, 303, and 304.
3. Descriptions of the Solenoids SOL353, SOL 355, and SOL 357 on lines 353, 355, and 357.
There may be others, but I got tired.
