[1] Sinclair-Scott was a maker of food canning machinery and in the early 1900s started to make car parts.

One of their customers, Ariel, failed to pay and in recompense Sinclair-Scott took over production,[1] moved the factory to Baltimore,[2] and marketed the car as the Maryland.

[1] The car was powered by a 30-hp[3] four-cylinder, overhead camshaft engine.

[4] The Ariel design was initially unchanged, and the Maryland was originally available as a four-seat roadster or a five-seat touring car.

[4] Production stopped in 1910 after 871 Marylands had been made, as producing the cars was not profitable.
