In 1959, Zenith introduced a line of budget minded sets to help them stay competitive. This line was called the Americana Series and featured the Royal 250 and Royal 275 in coat pocket radios, and the Royal 675 and Royal 710 in leather portable radios.

The Royal 250 (also known as the All American) was the lowest priced of the Americana Series at $39.95. It had a six transistor chassis and was made of a less expensive and less durable polystyrene cabinet. It was offered in only black, tan, or white. It had a plastic grill and a volume and tuning dial design that would be copied later in the 265, 275, 280, and finally the 285 in 1964. I’m not sure why so many similar models were made.
