This 1910 Wisconsin Special Speedster is said to have been constructed by a Brass Era enthusiast over the course of
several years, culminating in its completion in 2023. This unique vehicle is powered by a Type L T-head inline-six
engine from the Wisconsin Motor Manufacturing Company. It features three block and head castings, each
housing two cylinders, an aluminum crankcase, side valves driven by dual camshafts, dual coils, and a Hentschel
distributor firing two spark plugs per cylinder. It also includes a single Stromberg A-3 updraft carburetor and an
electric starter. The engine is said to have been overhauled during the car’s build with a bore increase from 5.10
” to 5.185” for a displacement of 697 cubic inches. The work reportedly included turning the crankshaft,
replacing the Babbitt bearings, and installing replacement forged pistons and stainless steel valves.
Power is sent to the rear wheels via a three-speed manual transmission and a Hele-Shaw clutch. An exposed exhaust
manifold leads to side-exit pipes located below the engine bay. Stopping is handled by rear drums with both internally
expanding shoes and externally contracting bands. Suspension incorporates a solid axle and semi-elliptical leaf springs
at the front and rear. Red-painted wood-spoke artillery wheels are wrapped in 36×4 Diamond tires, while a pair of spare
tires are secured to the rear of the car.
Based on a Mitchell Model S chassis, it features custom speedster bodywork finished in red with brass accents. The
frame and bodywork are finished in red with “Wisconsin Special” script on each side of the hood as well as
No. 10 graphics on the cylindrical fuel tank and the radiator stone guard. It also features a brass radiator shell,
acetylene headlights, leather hood straps, a frame-mounted storage box, and a Neverout kerosene tail lamp.
The car’s interior includes gray leather bucket seats. The wood-spoke steering wheel sits ahead of a brass-fitted
dashboard panel housing a Corbin-Brown tachometer, a range of ancillary gauges and accessories, and Wisconsin and
Selden Patent badges. Mounted to the driver’s right is a Jos. W. Jones clock and a Jones 60-mph speedometer,
the latter of which incorporates a five-digit odometer showing 300 miles. The right-hand-drive cockpit hosts a pair of
barrel-back seats trimmed in gray upholstery with nailhead accents. Additional features include brass hardware, black
floor trim, one hand-operated fuel pump for the passenger and driver, and a Pyrene fire extinguisher.
The car entered the care of the Dick Shappy Collection in October 2023 and is now offered in Providence,
Rhode Island.
The Mitchell-Lewis Motor Company of Racine, Wisconsin, produced a wide range of automobiles from 1903 to 1923,
including standard cars, trucks, and buses. It started out as a wagon maker before venturing into cars, initially a
regional competitor to the Auburn Automobile Company. Mitchell was an early adopter of four-cylinder engines and
later offered six-cylinder models, as well as a short-lived V-8 and V-12. It produced expensive vehicles from 1901
until 1938, and Mitchell cars gained a reputation for solid construction and quality, producing a variety of
models, including runabouts, touring cars, and limousines. A styling change in 1920, featuring a slanted radiator, was
not well-received, earning the nickname “Drunken Mitchell” and contributing to the company’s
decline. Despite strong sales in the early years, the company faced financial difficulties in 1913, leading to
changes in management and ultimately to its sale to Nash Motors in 1923, marking the end of Mitchell automobile
production.
Based in Milwaukee, the Wisconsin Motor Manufacturing Company began building internal combustion engines
in 1909 for a wide range of automotive, heavy-duty, industrial, agricultural, maritime, and stationary applications.
Wisconsin’s T-head engines were available in both four- and six-cylinder configurations and were utilized by
automakers such as Stutz, Pierce-Arrow, and Midget microcars in the 1910s. In the 1960s, it was acquired by Teledyne
Technologies. Although the Wisconsin brand is still recognized, the company itself was eventually sold to Subaru,
and its engine line was merged with the Subaru Robin division.
