[AMRadio] Help id transformer

[Gary Schafer]

I picked up a little gadget at a hamfest. It looks to be a low pass 
filter for audio. Has 3 terminals. In, ground, out. Made by UTC.
The number on it is UTC V-1284. Under that number is 363-1919G1.
There is also stamped on the side HQ48.
Can anyone identify this?

Thanks
