I need pin out information on an audio interstage transformer made for Hammarlund by UTC.  Thinking probably 1940's.

As best I can decipher on the worn paint, its labeled UTC-D ? 3551 and Hammarlund ?=31086-2.  IF anyone has any old transformer catalogs and has time to look, please see what you can find.  Rated for 3 watts, it matches a receiver output impedance of 7-8 kOhms to 600 ohms.

Thanks in advance for any leads.

Attached is a photo though I do. not know if they will come through.
