surely the dark crystalline finish to which the descriptions allude, an effect allegedly achieved by mixing naptha into the black lacquer prior to its
application to the wood*. However, it seems to be prone to flaking off and is frequently in poor condition or missing from these models when
found today. Fortunately mine is still in excellent original condition.

The original purchase price of the 557 was $39.95, about the same as for the model 566 Bluebird of the previous year.
Sparton Model 557 "Sled" Blue-Mirror Radio (1936/1937)
Sparton 557 Sled
Sparton 557 rear view
The Sparton model 557, the first of
Sparks-Withington's mirrored "sled"
radios, was introduced in June of '36,
almost a year after their celebrated
Bluebird. These sleek and wonderful
sets, attributed to Walter Dorwin Tea-
gue, are bold reflections of the mid-
century streamlining movement. Quite
understandably, they have gone on to
become highly revered and collectible
icons of the Art Deco radio era.

One newspaper advertisement from
1936 proclaimed the model 557 as
...a radio of chrome and crystal
The chassis of the 557 is an ac-
powered 5-tube superhet covering
standard broadcast (540-1720kc)
and shortwave (5900-17,500kc).
The tube line-up is:- 6A7 (mixer/
LO), 78 (IF), 75 (2nd det/AVC/1st
AF), 42 (AF output) & 80
(rectifier). The three knobs are,
from left to right, on/off/vol, band
selector and tuning. The design is
very similar to that used in the
deluxe model
558 sled introduced
a year later. That model however
added a tone control and switched
to the latest octal-based tubes.
while an extract from an original Spar-
ton ad for it can be seen to the right.

The references to "rare" and "fine"
woods in these clippings constitute a
touch of advertising hyperbole, as the
wooden elements of the cabinet are in
fact composed of common, if not eleg-
antly contoured, plywood. It is however

Newspaper reports reveal that the Sparks Withington Company (aka Sparton) adopted a novel approach to introducing and promoting their
1937 line, which included the model 557 sled. The line had been originally presented in June of 1936 to an audience of over 250 radio dealers
at a convention held in Jackson Michigan, Sparton's hometown. However, in early July, as part of a drive to increase their radio business by
80%, they took the show on the road, or should I say, the rails. A
 Pullman car, nicknamed the Sparton Special, was outfitted as a travelling
exhibit, complete with executive office, fifteen Sparton executives and supporting staff. For over a month, starting in Jackson, this Special trav-
elled a 7000 mile loop through Central and Western states, making 26 stops, including Salt Lake City, Portland, Seattle, San Francisco, Los
Angeles, Phoenix, El Paso, Dallas, Houston, New Orleans, Memphis, Louisville, Cincinnati, Dayton, Columbus, Cleveland and Detroit! At each
of the stops, dealers and key account holders, who had been telegraphed invitations prior to the Special's arrival, visited the exhibit to view,
hear and learn about Sparton's 1937 home radios, refrigerators and auto radios. Advertising was prepared for release in each city visited, with
much of it placed in the local newspapers as part of what was one of the largest publicity campaigns in the company's history. At the outset, it
was hoped that by the time all was said and done, at least 5000 dealers and distributor's salesman would have attended the exhibit.








Also among the 15 executives along for the ride were Harry Sparks, General Manager; William Sparks, President; Charles Kayko, Factory
Superintendent; Harold Nielson, Sparton's chief radio engineer; Alex "Scotty" Smith, District sales Manager, and Guy C. Core, Advertising
Manager. Radio Weekly's Curt Wessel went with them too. With the company's key executives mostly all on the train for a period exceeding
one month, business that would ordinarily have been transacted from the factory was handled from the Special, which was outfitted as a rolling
administrative office, complete with secretaries. The car was painted its entire length on both sides and bore the slogan "SPARTON. Radio's
Richest Voice". What a trip it must have been!

At the stop in Ogden, Salt Lake City, it was planned to have over 200 Sparton dealers and key account holders from the surrounding territory
visit the exhibit while it was parked at the Union Pacific Railroad Depot all day Wednesday July 8th. The car arrived at 7.30am that morning and
departed for Portland, Oregon, that evening, ahead of it's sweep down the West coast.

How successful was this sales jaunt? I've been unable to find out the final tally, but if the $250,000 in orders taken after just nine of the twenty
six stops, as allegedly stated by Art Haugh to a reporter in El Paso, was any indication, I would have to say very! Moreover, a report in the
August 1936 edition of Radio Retailing paints an even rosier picture; it states that by close of business in Los Angeles, several stops
before El
Paso, total bookings of $432,000 had been made! One of these reports however would seem to be incorrect. Radio retailing also notes that
the train departed Jackson on July 14th, but this is for sure incorrect, as Salt Lake City newspapers published on the 8th report the Special as
due or having arrived in their town on that day, a chronology consistent with that provided by other publications made later in the journey.

1937 Sparton Radio Special
The Special Pullman, which cost $48 a day to charter, was headed by Arthur T. ("Art") Haugh, Sparks-  
Withington's General Sales Manager. Company executives had initially decided upon the trip as a means
of taking Sparton products to the dealers who had not been able to make the recent Jackson convention.
During an interview with a newspaper reporter at the stop in El Paso, Haugh is on record as having said
"
This is a bit of pioneering, going over the country with our merchandise in a Pullman car. Formerly we
brought dealers to the factory. We already have taken more than $250,000 in orders and have made only
nine of our scheduled 26 stops
".

The new Sparton radios received acclaim far beyond fondest expectations. Everyone agrees that Sparton offers the biggest
"eye-full" and most amazing "ear-full" in 1937. The outstanding opportunities are readily apparent. With such smartness of style, such
cleverness of design, such quality of reproduction, and such a distinct price advantage, dealers recognize the record rapid-turnover
volume that is in sight. The surprise of the season, Sparton should prove to be a fast seller and quick money maker. Investigate NOW
