Been a while with this thread and not sure you ever got an answer to your question.
It's more a process of elimination and deduction than anything else, but from all these wireless boxes I have been able to inspect, the most likely candidate for storing in the angle iron frame on top of the spare wheel bin is the remote control units. The Nearby RCU would be perfectly located there for connection to the wireless control box in front of it and a short run of land line could be readily fed to the two terminal posts on the wall underneath the cypher clerk's folding table. There are also a couple of tin shelves readily available for storing the extra Cells, Cry, X Mk II, needed for the two RCU's.
For the longest time, the only RCU's I knew of were the Wireless Remote Control Unit No. 1 (Canadian) built by RCA, NE and DE here in Canada. They size in at 12.75 x 9.75 x 7 inches and 22.25 lbs each. The footprint is a bit small for the angle iron bracket, which seemed odd for many years. Then I became aware of a number of other styles/versions of remote control units, which were probably also in service and capable of working a 19-Set. Still have no idea how any of then size up dimensionally, but it is quite likely the bracket in the wireless box is a 'catch all size' to readily accommodate whatever was available in the supply system.
The other odd thing about this rack was I have never seen one with any form whatever of surviving canvas straps. Always missing. Every other possible canvas strap, inside and out for these wireless boxes showed up sooner or later in situ, but never these. They seemed to be a popular item. Eventually it occurred to me that perhaps the bracket setup on the spare wheel bin was meant to hold the Nearby RCU on the bottom and the Remote RCU was stacked on top of it when not in use. It would be logical to keep them together in the Wireless Truck. In order to hold down nearly 45 lbs of kit, however, one would need a long and hefty canvas strap assembly, kicked up a notch as it were from all the others on the truck, That would make those straps much more useful and more likely to disappear from the trucks.
Be interesting to start a Remote Control thread in the Wireless Section here to document all the versions known to be out there, sizes and what wireless sets they could work with.
Cheers,
David
