Even more important, how to do it safely to operate the set?
So far this connector seems to be in dirty but near complete condition. The only missing item I can currently identify is one of the four corner screws holding the main body together is missing. Hopefully that will be an easy fix. There is a bit of sulphate deposit on the two banana sockets on the back of the plug assembly and the large mounting screw has some surface oxidation that should also clean off easily. All the raised letter identifications cast into the bakelite are intact and still have their white paint highlights.
The Parts List states the two leads should be black and red. The ‘red’ one on this item looks more tan/brown, but that just might be decades of dirt accumulation. I took a look in the manuals to see where this item was normally stored and it took me a few moments to realize it was an active part of the 52-Set and would always be fitted to the front of the Supply Unit. Doh!

I've cast up some bodies for the Connector, Twin No.17 and am sourcing out the guts and cables (any idea where I can get the proper fabric covered cable?). One had your name on it but I think you're OK now. Good find!!!
A couple of details I've noticed. The face plate on yours has rounded corners and my original is square. Your screws may have washers but aren't the star washers on mine. This connector was used for the 52 set but also the No.9 Mk.1 and No.9. Both those manuals have pics that show one cable darker than the other so I expect 'red/black' cable colours were from the beginning. The British No.9 set must have had a similar plug and I wonder what it looked like.
