Model 557, Spectacular blue-mirrored radio from 1936 
with chrome fins and a black laquer napthaline finish 
on the wood "sled" frame, am and shortwave bands. 
A "Deluxe" version was available, the model 558, 
which sported more etching on the mirrors and four knobs (a tone control was added). 
Peach colored mirrors were also an option with each model. 
The "Sled" radios followed Sparton's success with the round mirror "Bluebird" radios.
