Right found piece of paper.
It’s all Scribble but I’ve put 9 as CT
8-10 99v
8-9 49v
9-10 49v
Plus 24v reading which is or looks like I wrote 6 & 7 added together so obviously 12v each.
Transformers are not my forte but that’s obviously the readings I measured.

Obviously the other taps are for 115 or 230 on input side.

To be honest it’s a beauty and workmanship is top spec in my opinion.

Hope that helps if not I’ll take some readings tomorrow.

OK but all that beauty will need to fit in a project of a member.

Maybe you could advertise is as being a military transformer with 115/230V 50 Hz primaries and 2 x 50V and 2 x 12V secondaries (all with a central CT
so likely not separate windings). Now the question will follow how many Ampères the 2 x 50V and the 2 x 12V secondaries can deliver.
