Yay, more Collins gear! I've had one of these on my eBay watchlist for years, lol. The older 51y-4 ADF Receiver is all electromechanical. There is a video on TH-cam showing the inside.
The tiny, tiny relay almost looks like a late stage design addition. It might be switched by the button on the front panel to select the test port or perhaps to monitor an additional two tests signals with just two diagnostic meter connections.
Simple solution, expand the storage. That tuner is mix of nightmare and a dream. Wery good construction of the whole unit, esp modularity for service. It whoud be nice to know how reliable it was in use...

Hmm, Never seen a popular channel video with no comments. Keep up the good work.
Silver is attacked by sulphur compounds in the air. Ammonia based silver polishes can remove it if I recall correctly.

True, Keep up the great work
