I guess its quite possible the top unit was in fact a No. 6, but its speculation and fervent hope 
An upgrade unit perhaps?
and yes....the tubes, which I assumed (that mother again) was some sort of vent, is wired!

They will be for different charging voltages and currents, I suspect. I have no idea how they work but suspect it's the equivalent of the old vehicle "control box" for regulating the dynamo charging the battery to prevent overcharge.
There's an aircraft one on ebay for 25 GBP or so (which is a silly price) as I think I paid 1 GBP for these. That one (with A.M. stores code) is 24V.
We need a section ZB VAOS from WW2 or thereabouts!
Chris.
(I thought the tubes were vents, too!)
