[Milsurplus] Unknown Navy transformer ?

[Hubert Miller]

Here is a unused transformer from a Navy marked box.   It looks to me like a power transformer. Sorry, no size reference in photo. I found a couple
smaller ones, maybe audio ? with similar style and with last number of the part number different. I thought maybe someone here would maybe
recognize what specific equipment this was found in.  I can ohm it out and put the low number pins on a variac. I suppose the smaller transformers
I could do some kind of ratio at 1000 Hz test, but I likely won't.
