“Bruneau”

-On the crankcase casting we can see the letters "S.G.D.G. Bte "=" Patented: Without the state guarantee ".

-This phrase is shown on most engines from the first half of the twentieth century, as the state (French) gave the patent, without taking responsibility for the product.

-But what most attracts the attention is that they had to put it in a clear visible way next to the brand name. See Anzani, Hispano.Suiza, etc.
