[Hallicrafters] ?? transformer identification

[Walt Cates]

I have what I think is an audio output xfmr (NOS).  It has the numbers 33P322  and 1052. The primary winding (red & blue) looks to be about #20 or 22. The secondary (green & black no tap) looks to be #18 or 16. The resistance is less than 2 ohms, primary and secondary. It is an open E I iron core 2 1/2" X 1 7/8".  It was in a batch of surplus parts I got from Wilcox/Hallicrafters in 1977.
 
Can anyone identify it.

Best Regards, Walt Cates, WD0GOF
