Although not expressly intended for racing, the 512BB enjoyed a fairly long racing career. After an initial configuration, with three cars that participated in the 1978 24 Hours of Le Mans, the 512BB was developed with the help of the company in a more massive way, with completely revised aerodynamics and further prepared mechanics. These cars (512BB-LM) were sold to various customers, such as NART, Ecurie Francorchamps, Charles Pozzi, Scuderia Bellancauto and other professional level teams. In 1980, a development was perfected, which among other things led to a weight reduction of around 120kg and improved aerodynamics. Having never been homologated in Group 5, the 512BB-LM raced in the IMSA-GTX category, sometimes obtaining good results although often lacking in reliability. These cars were used in the World Endurance Championship and IMSA until the mid-1980s.
Brumm was founded by Reno Tattarletti, former Rio sales director, with Emilio Molteni and Virginio Bianchi in Como, in 1972. The company name comes from a model of carriage (from "Brougham") widely used in Milan in Nineteenth century. Brumm originally made 1:43 scale models of horse-drawn carriages. In the mid-1970s, steam-powered vehicle models went into production, and in 1977, classic car models. Car models, mostly sports and racing cars, along with some small Fiats, soon became the company's most important and successful product line. Since the mid-1980s Brumm has regularly produced limited edition models in special and promotional liveries. Proudly continuing to produce in Italy, Brumm is today very active, with a very rich catalog that offers updated variants of already known moulds. Completely new molds are nowadays rare, such as the Fiat Panda II Series, which was long overdue.
