  • Notes
  • The Gimbel branded ZR-4 was actually the Chelsea Model 122 which Chelsea was currently selling under its own brand name.

    The only difference between the ZR-4 and 122 was that the Model 122 mahogany cabinet went from slant front to rectangular, saving perhaps a few dollars of production costs. All the other components, layout and design of the two was exactly the same.
