Help me identify these transformers

[DefQon]

What are these? 2 of the smaller ones look like OPT's of some sort and the bigger a power transformer.

Any idea what these are for or possible specifications for them?

They look to be out of some 30-40's military unit.

They really do scream military!

Why not run 6.3 VAC through one winding on each, then the voltages found on the other terminals. Watch that you might very easily have your mains voltage on other terminals! So measure very cautiously.

They weigh alot as well which is always a good sign for decent iron.

Are you going to try my suggestion?

BTW, I agree with you on Philips.

Be careful, they could very well be designed for 400Hz and could end up in smoke if connected to 50/60Hz

I probably will Anatech, amongst others as well.

An externally hosted image should be here but it was not working when we last tested it.

Hi Elvee,
Thanks, I completely forgot about that! Great point.
