1974 Brain Box saves the day.
OK got this 4 pin control module cut open, looks to me like an old school board from the '70s.
Probably just some old stock box.
The external transistor mount bolts were well insulated from the box with large plastic washers, with the 2 prong transistor plugging into the board from the top.
