Hi William,

I will call Osborn tomorrow with spec plate in hand, They will be interested
in this relic I think. The windings are superbly wound torriods. The plate
only says 480v to 240v transformer.

sounds vaguely like a saturable core reactor - could it have worked with an
external capacitor?  does it say "three phase" or could it be single phase?
Another way to chase this down is to see if Osborne owns patents related to
"transformer"
