MT4 Long read:
This stunning OSCA MT4 boasts a captivating history meticulously researched by its owner, who devoted seven years to its restoration.
Constructed in the summer of 1956, chassis number 1176 was delivered to its first owner, Jim Simpson Jr., in the US that October. Remarkably, it marked Simpson’s fifth MT4 acquisition, establishing him as the largest single buyer of this model. Different from other OSCA’s in that year, this one was delivered from new with a 10 cm longer 2300mm wheelbase. The unique berlinetta body was designed by Ernesto Maserati and meticulously crafted by Morelli of Ferrara.

Chicago-born Simpson, a loyal OSCA customer with substantial MT4 racing experience, was a Republican congressman in the 1930s. Educated at Harvard and owning farms in Illinois and Virginia, he funded the Simpson Special—a streamlined MT4 that set numerous records at the Bonneville Salt Flats in 1955.

Unfortunately, Simpson’s ownership of 1176 lasted only a few months before a public road incident led to the destruction of its body. Subsequently sold, the car became the foundation for an incomplete barchetta project, displaying crude chassis repairs on the passenger side front. The car then disappeared until its acquisition in the early ’80’s, along with several other OSCA MT4s, by Peter Kaus’s renowned Rosso Bianco Museum in Germany. Documented as both a berlinetta and a barchetta in the late ’80s by John De Boer during a visit to the Kaus collection, this information is featured in his 1994 book “The Italian Car Registry” (p.271).

In the meantime, its engine, numbered 1526, found a new home in the late-’70s, residing in chassis number 1183.

Fast forward to October 2007, the rolling chassis found its way to the current UK owner, a notable marque enthusiast and racer. He delved into the history of 1176, particularly its original coupé bodywork, consulting drivers who knew Simpson and family members. Despite an exhaustive search through major photograph collections, no information surfaced. After six years and consultations with fellow MT4 owners and experts, the owner opted for a barchetta body, mirroring the one constructed on chassis 1174 by Morelli in the same period.

In 2016, the factory drawing of the coupé body surfaced, discovered by Alfieri Maserati, a copy of which is included in the documentation.

Meticulously restored between 2009 and 2014 by marque specialist Autofficina Aldo in Bassano and Carrozzeria Garuti in Reggio Emilia (the fourth body of its kind produced by the latter), the OSCA features a 1491cc twin-plug engine crafted by the renowned Hall & Hall in Bourne. The original magnesium sump and oil pump were mated to a new block, one of 12 cast by Hall and Hall using an original as a model, and a correct twin-plug head. Numbered ‘1500N’ (for nuovo), the engine produces nearly 120bhp on fairly soft road cams, making the car very easy to drive on the road. (Hotter cam profiles would obviously give around 140 bhp). Missing parts were crafted from the original moulds acquired directly from Alfieri Maserati (the keeper of the OSCA archives). The ZF S4-15 gearbox, correct for the MT4, was rebuilt in 2015 and features a remote lever.

Inside, the spartan yet surprisingly spacious cabin features only essential information one would expect from a competition car: revs, water temperature, and oil pressure. The twin side-exit exhausts emerge on the driver’s side, allowing drivers to easily evoke the 1950s road races in which these little OSCAs excelled.

This OSCA MT4 has participated in prestigious events such as the Gran Premio Nuvolari, multiple Leggende di Bassano, Circuito di Avezzano, Gaisbergrennen, and more. It is supplied with a FIVA identity card and includes a CD of photographs depicting the body build, another CD of the engine build by Hall and Hall, along with an extensive file chronicling its research history and restoration journey.
The car has been very well maintained, needs nothing and is ready for any event.
