The story
The company which built the Ruby cars and engines was called H. Godefroy et Lévêque and was located in Levallois-Perret, in northwestern Paris. In 1909 they began building automobiles under their own names, the production of which ended by 1922. After the building of automobiles came to an end the company proceeded to develop and sell proprietary engines to a large number of small light car manufacturers. Some of the earlier cyclecars were marketed under the "Super" brand until 1919 or thereabouts.
