This is a National 1106 model by Valco (Supro) with two Supro single coil pickups and the original Piezo bridge pickup system with six volume pots to individually control each string. Ebony fingerboard. The pickups are a Keller design for Valco, and I'm including the patent drawing.
It was re-fretted last year and has zero playing time since then.
Original case.
