(see perhaps Metallurgic and La Metallurgique).

-A 26 CV water-cooled Metallurgique engine was fitted on the Howard-Wright biplane in 1909.

-Another 4-cylinder engine that was water-cooled as well gave 32 CV at 1,850 rpm and weighed 300 lbs.

-And there was another one that gave 49 CV at 1,600 rpm. This engine weighed 550 lbs displacing 454 cu.in. This could be a six-cylinder.

From Appendix 7: By 1912 this company offered three models of aviation engines.

-All of them had 4 cylinders and were water cooled: 40 CV, 60 CV and 90 CV.

From Appendix 12: In this ad from their English dealer we can see the cylinder details and the position of the magneto.
