erla and what is it?

[Buzzsaaw]

Question for you that might have seen this model.

I've been getting back with all my "started" radios for restoration. This ERLA upright is on the bench. As I was removing the chassis I noticed.. hay.. no Antenna!.. There's two leads coming out the back of the chassis and hanging down below the board that the Chassis was mounted to. Grabbing the flashlight, I could see were there's a mark on the underside of this board where possibly the Antenna could have lived. Here's a pic looking up at the bottom of the Chassis mounting board.:



You can see the 3 holes for the chassis mounting screws and over to the right what looks like a large slot I presume is for the speaker wires (5) and the power cord. You can see the "band" from left to right where the antenna could have been.
I thought of buying a wave magnet or some such antenna but finding out just what was there would be interesting. I could also build one using a board form of the appropriate dimension and winding a coil on.

But I'd like to find out what is "original stock" for this radio.
