I looked the name up, but only found one mention of this specific model online.

I see that there are many Victor and Columbia look-alikes that they made, but I can't seem to find much info on my model. Interestingly, it doesn't have a horn. At first I assumed that the sound was supposed to reflect off the floor, but I found the remnants of a volume control lever inside the cabinet. I assume that the mechanism that controlled the sound was connected to the horn, and it had to be removed with the horn. I looked under the turntable and saw the OKeh logo. Was the turntable replaced, or is it manufactured by OKeh for Stradivaria? The serial number is 6818 if that helps. It is full of generic black record albums, and the motor is manufactured by the Meisselbach co., which is located in Newark, NJ.
Thanks in advance for anything you find!
