Hard to tell yet. Could it be an EMG35-size soapbar? Plenty of replacement options if it is. Or it could be a TB+ size pickup with different innards.
Or even the same innards with an arbitrarily different name, who knows
It does say there's a coil tap pull switch, so at the very least it's got 4-conductor wiring on the output, which I don't think the TB+ ever had.
From zooming in on the picture, the corners look more rounded to me like the TB+ than like the EMG 35, which are nearly square. But that's not a lot to go on.
