Pye Telecomms transformers?

2 Attachment(s)

Found this pair of miniature transformers in one of my many junk boxes. They were taped together and I suspect they are transistor audio driver and output pair.
Anyone recognise them? Maybe I should ask in the Amateur section as they might have come from some old vhf gear?

I'm guessing that they may be from something like an AM10 Cambridge [the series that had transistor modulator but a QQV03/10 valve PA?]

Screenshot from the Cambridge manual, does the larger one have a part number anywhere.

Part number looks like 277892 so audio o/p.
Thanks both for speedy solution.
I'll stick them in the right forum section in case anyone wants them.
