Here are Vintage 90's Schaller Black Left In Line German Made Machine Heads. These are new and have no box as they were bought in a bulk tray. They came this way from the factory at a company event where C. Bruno Kaman, who owned the Ovation brand of guitar, was having a factory sale. The machine heads are of the finest German made Schaller which were used on Ovation guitars. These require no screws and have a small tenon that go into the wood of the head stock when the bushings are tightened.
