Daniel, I think, is on the right track as to the contents of the filter box, but I can probably put a finer point on it.

It's a Collins radio, and probably uses Collins' famed, high performance and rather fancy mechanical RF filters. I think Bulova was a subcontractor on some - and it makes sense given their experience with resonant elements in about that frequency range on the Accutron.
