Default can anyone identify theses OT markings?

i have 2 transformers that were pulled from a large wurlitzer organ (i think maybe lowery?)

one of them is marked;

W.TT
117782
4573

the other;

p1.10
117782
2900

each has one white and one black wire and both look identical in make.

i was just trying to find out some specs on them, and way to test them?

thank you much

a choke is a single winding inductor - one wire in, one out.

Typically it is used in a power supply to smooth the ripple in the supply.

A Transformer has two (or more) windings and typically is designed to match the voltage (or impedance) of dissimilar supply and load.
