Let's try this:
Cottin & Desgouttes:
In 1907, the company also produced a 9.5-liter, 30 hp, six-cylinder model, as well as a 2.5 liter, 12 hp model that was so well accepted by the public that is was produced without any major changes for more than four years.
Prima (France):
1906-1909 Ste des Automobiles Prima, Levallois-Perret, Seine
These cars were made by Leon Lefebvre who had previously been responsible for the BOLIDE. In 1906/07 two models were listed, a 9hp single-cylinder and 10/12hp 4-cylinder, and for 1908 the single was joined by larger fours of 12/15 and 20hp. Eash type was available on three wheelbases, and wide range of bodies was offered, tourers, doctor's coupes, limousines, landaulets, delivery van and trucks. They had unit construction of engine and gearbox, which was very advanced for the time. Two cars were entered in the 1907 Coupe des Voiturettes that did not distinguish themselves.

The link: Both companies manufactured a model with very similar power units at (almost) the same time.
