Notes

“Cadran Tachymétrique breveté S.G.D.G., système A.T.”

This patented dial was especially made for the car drivers. This dial indicates without calculation, by simple reading, the speed of the car by the hour.

The “système A.T.” refers probably to the invention of the French Captain Arsène Thouvenin, Paris, and its “Phonotélémètre” (Swiss invention patent No. 10 870, dated July 13, 1895).
