The logo on the bottom part of the horn should say, "RCA Victor" and there should be a black and white dog (dalmation?).
In the Old Days a horn like that could take the vibration of a phonograph needle in a phonograph record and make it loud enough that people could dance to it in the school gym. Not the people of today and not the noisy gym of today. But soft music, soft partner, fluttering heart all seemed to work fine---all done acoustically, no electronics, in fact probably no electricity. Most of these machines were wound up with a hand crank.
Ah, "The Good Ole Days." Or translated: "Poor Memory."
Enjoy,
