Though National remained financially buoyant in the early 1930s, the company was in considerable turmoil. The principal cause of this was the legal action initiated by Dobro, who alleged that their rival resonator-making business had been damaged by falso statements made by National’s General Manager, George Beauchamp.

Beauchamp was sacked from his post at National in 1931. The resolution of the dispute with Dobro led to a rapprochement between National and the Dopyera family.

In July of 1935, Dobro and National merged. Under this new regime, National continued to make both metal-and-wood-body resonator instruments, including the elegant birch plywood Rosita model illustrated here.
