[Milsurplus] Unknown IF Xfmr

[Michael A. Bittner]

I picked up some small IF transformers at a swap meet that are obviously Mil surplus spares judging by their construction and fungus treatment.  The cans are 1" x 1-3/16" base x 1-7/8" tall with two holes in the top for access to two slug-tuned coils inside.  One hole is marked 175 KC, the other is marked 2 MC.  Numbers marked on the sides of the cans are:  CWS165338 and 198451.  Anyone know what equipment these came from?  Any help is most appreciated.  Mike, W6MAB
