I've been reviewing everything that has now been written here about this PSU: let's summarise.
1. It's very likely that this PSU and the PSU for an Eddystone 358X were made by the same manufacturer.
2. The PSU for the Marconi CR.300 has strong similaraties to this PSU.
3. This PSU is not for a 358X nor a CR.100: we don't know what receiver it was made for.
4. So, the list of possible manufacturers of this PSU are: (a) Eddystone, (b) Marconi, © some other company.
5. Somehow the idea that Marconi built this PSU and the one for the 358X seem highly unlikely. Similarly, the idea that Eddystone built this PSU and the one for the CR.100 seems equally unlikely. Hence, we are left with 'some other manufacturer' as the most likely explanation. As for whom, I really wouldn't want to hazard a guess.
6. As for what particular receiver this PSU was made for, the possibilities are wide, but reviewing what I wrote earlier, the Eddystone S.358/1 (low power AF output stage), the S.358X, S.400, S.400X and the S.400B, (a.k.a. the Air Ministry R.1448) all seem to be strong contenders.
And at this point in time, that's as far as I can go with this: HTH.
