My recollection was a little fuzzy on some details. The wiring is made
up of wires with crimp terminal plugs on the ends and each relay socket
terminal has two receptacles for the wires. The relay moving contacts
are actuated in a group by a plastic piece connected to the armature.
The each moving contact consists of two fine (#30) gold wires. The
narrow relays have 4 Form-C contact, the intermediates 6 and the wide
The plug and terminal strip are not part of the base socket frame, but
were likely made by us and then added to the frame.
The date code on the chassis says 1976, so this is probably the last one
built and then cannibalized for relays to send to customers.
After looking at it, I wish that it still had the full compliment of
relays. It might be interesting to make something out of it.
