In the years 1909 - 1914, the workshop admonition at the Avancefabriken, E H Nilsson, made a number of shell models of the Avance crude oil engine R1. Six of Nilsson’s models are preserved, four are in the Technical Museum’s collection. The Advance Engine was a two-stroke ignition engine manufactured by AB J V Svensson’s Motor Factory in Augustendal, Nacka. J V Svensson intended to make cars, when he founded his business in 1899, but instead came to focus production on ignition engines. J V Svensson’s Engine Factory was first in Sweden to manufacture two-stroke ignition engines, using the American Mietz & Weiss engine as a model. All former ignition engines worked according to the four-stroke principle, but through the introduction of the two-stroke engine, the Avancefabrik opened up to a very significant development of Sweden’s engine industry: in Sweden, over the course of the years, manufacturers would absorb the production of two-stroke ignition engines. The former engines were driven on kerosene, but crude oil was used as fuel from about 1908/1909. The workshop driver E H Nilsson’s models are precise miniatures of the Avance standing single-cylinder crude oil engine from the period around the 1910s. The type is known as R1, and could be ordered in varying sizes with effects from 6hp - 90hp. Type R1 is a stationary engine. The factory also produced boat engines and transportable engines (so-called motor locomotives). The Avancefabrik was only when in 1912 it began to produce engine plows for agriculture, a precursor to what is today tractors. J V Svensson’s crude oil engines became very successful in the 1910s both within and outside Sweden’s borders: In 1917, the Motor Factory had its largest single employer in Sweden. The Russian Revolution, however, was a major setback for continued exports, and the company went bankrupt in 1922. After a reconstruction, the activity was resumed as AB Avancemotor, which was bought up in 1929 by Munktells. E H Nilsson’s models are stamped with unique serial numbers. Models 1 - 3 were probably used as demonstration models for the factory’s customers, and models 4 - 6 were handed over as gifts. According to E H Nilsson, three more copies were produced. Model no 4, TM15605, went to Bertil Egnell, CEO of Marstrand’s Mechanical Workshop. Egnell had been granted exclusive rights on the sale of Avancemotors in southern Sweden. The second copy of the dedication went to J V Svensson himself (No 5, TM17244) and the third to B A
