marconi: Marconi diversity receiver

When I came across these images, I did recognize the set from somewhere - yes: at HMS Collingwood Radio Museum I have seen a marconi diversity receiving system with a very similar aspect.


The upper three units turn out to be three tuning units for diversity reception,
the reception of the same station / channel from different antennas to reduce fading (antenna diversity) or even reception of the same programming from different frequencies (frequency diversity) improves readibility of a signal:
Upper tuning unit:


and here the image of the middle tuning unit:

So in my opinion the set from Radio Schweiz is not a unique set, but built to customers specifications from different modules.
Hopefully, we might find more informations about this set or similar systems and what they might have been used for,
