Page "Dobro" Paragraph 11

From the outset, wooden bodies had been sourced from existing guitar manufacturers, particularly the plywood student guitar bodies made by the Regal Musical Instrument Company.

Dobro had granted Regal a license to manufacture resonator instruments, and by 1937, it was the only manufacturer, and the license was officially made exclusive.

Regal continued to manufacture and sell resonator instruments under many names, including Regal, Dobro, Old Kraftsman, and Ward.

However, they ceased all resonator guitars production following the U. S. entry into the Second World War in 1941.
