• Notes
• Beitman 1960, Vol. 20, page 36 lists this radio as model 880 Explorer. The description reads "These sets utilize an etched circuit board chassis 120374 and 120485 identified by part number 630225 and 630243 respectively. The part number can be found on the etched circuit board side of board. A paper label located on the external jack, containing the last three digits of the chassis number, is another means of identification." Image evidence of the paper label as well as of circuit boards leads us to the conclusion that Beitman has the model number wrong.
