The lucite posts are a bit of a puzzle and in any event this looks incomplete, having no coupling between cavities. The big bathtub area gives space for a lot of discrete coils, semis, etc.

There seems to be small holes at the bottom from the square areas to the round areas, so apparently a capacitive or inductive probe will be later inserted into those small horizontal holes.
