Yes they did; that was a legacy from acquiring the Hotchkiss Engine Company, which was of French origin. Prior to using the Hotchkiss design, the early Bullnose with the American Continental engine used a bewildering mixture of BSF, Whitworth, Metric and American Fine threads.
Similarly Georges Roesch used metric fittings with imperial heads on his Talbots.
