Overview
Shad-Wyck was an American automobile marque associated with the Shadburne Brothers, automobile dealers from Chicago. The marque operated during the late 1910s, with manufacturing based in Frankfort, Indiana. Its initial automobiles appear to have been rebranded versions of Bour-Davis cars rather than wholly original Shad-Wyck designs. The Shadburne Brothers had acquired Bour-Davis and moved production from Detroit to Frankfort, creating the industrial and commercial basis for the Shad-Wyck name. The brand's name was evidently intended to evoke the better-known Chadwick automobile marque. Its promotional presentation also reportedly used images of the Roamer, another contemporary American automobile, rather than consistently depicting an identifiable Shad-Wyck product. These practices suggest that Shad-Wyck was positioned as a new automobile name built around existing manufacturing resources and borrowed visual associations, rather than as a fully established independent engineering brand. Shad-Wyck automobiles were manufactured from approximately 1917 through 1918. The company announced that it would eventually produce cars of its own design, but available historical accounts cast doubt on whether such independently designed vehicles were ever completed or placed into regular production. The underlying Bour-Davis business was subsequently sold to the Louisiana Motor Car Company and moved to Shreveport, Louisiana, where production continued under that separate enterprise until 1923. The Shadburne Brothers later returned to Chicago. A further line of Shad-Wyck models was announced as late as 1920, but no cars are known to have been manufactured from that later announcement. As a result, Shad-Wyck is generally treated as a defunct, small-scale American automobile marque whose documented production was brief and closely connected to the Bour-Davis operation. Its historical significance lies less in surviving market scale or technological influence than in illustrating the fluid relationships among early American automobile dealers, manufacturers, acquired marques, and rebranded vehicles during the industry's formative period.
History
Shad-Wyck emerged during the expansion and instability of the American automobile industry in the late 1910s. The enterprise was run by the Shadburne Brothers, Chicago automobile dealers who became involved in automobile manufacturing through the acquisition of Bour-Davis. Bour-Davis had previously operated in Detroit, but after its purchase by the brothers, production was transferred to Frankfort, Indiana. The first Shad-Wyck offerings appear to have been Bour-Davis automobiles sold or presented under the new Shad-Wyck identity. This indicates that the marque initially relied on an existing vehicle design and manufacturing operation instead of beginning with a clean-sheet automobile program. Contemporary promotion reportedly used imagery associated with the Roamer automobile and selected a name resembling Chadwick, a more prominent automobile marque of the period. The branding therefore sought to create recognition through association, although the surviving historical record does not establish a substantial independent Shad-Wyck product range. The Shadburne Brothers stated that they intended to build automobiles to their own designs. Historical accounts, however, question whether these proposed original models ever reached production. The documented manufacturing period for Shad-Wyck is generally given as 1917 to 1918, making it a brief-lived participant in the American automobile market. The Bour-Davis operation did not remain under the Shadburne Brothers indefinitely. It was sold again to the Louisiana Motor Car Company and relocated to Shreveport, Louisiana. Production under that separate company continued until 1923, but this later activity should not be treated as continued Shad-Wyck production. The Shadburne Brothers returned to Chicago, yet they continued to announce Shad-Wyck plans. A new line of models was publicized as late as 1920, although no automobiles are known to have been made from that later program. Shad-Wyck consequently ended without becoming a durable automobile manufacturer. Its brief history reflects the era's common overlap between dealerships, acquired factories, renamed vehicles, and ambitious but unrealized model announcements. The marque is now remembered as a defunct American automobile brand with a close historical connection to Bour-Davis and a documented production life of roughly two years.

Shad-Wyck automobiles
The marque's documented vehicles were American passenger automobiles manufactured in Frankfort, Indiana. Early offerings appear to have been Bour-Davis cars presented under the Shad-Wyck name. The available historical record does not establish a clearly documented range of independently designed Shad-Wyck models, and a later announced line apparently did not enter production.
