Hey folks,
My French brother-in-law gave me his father’s Chauviere 2-blade metal propeller (about 6ft in length). I appears to be from 1920 but I could be wrong. What I am wondering is what type of aircraft would this have gone on? I can’t find much of anything about it on the internet or at the library. Lots of stuff on wood props but next to nothing on early metal ones. Any help would be greatly appreciated.

The seaplane could be a possibility if the engine was ungeared, i.e. there was no gearing to reduce the prop RPM below the engine RPM, usually around 2:1 depending on the application.
Many engines in the inter-war period did not utilise reduction gearing, the prop being attached directly to the front of the crankshaft. Gearing allowed a bigger prop at a more efficient lower RPM. Basically the bigger the engine the more likely it would be geared down at the prop. 400hp is more in the larger engine category but it is still entirely possible it used direct drive – especially pre-WW2.

Thanks! What I was able find was Gourdou-Leseurre (GL) 812 HY and 813 HY, French naval catapult seaplanes used Chauviere metal props. But they operated at 400hp so this one might not be suitable.

What a beauty.
I know nothing about its background but I’d say, from the diameter, that it would have been fitted to an engine to an engine of around 100-200 h.p. which makes it suitable for a large light aircraft, possibly a touring type.
Not much, I know. Best thing to do is to study pictures of aircraft of the period and see what looks similar. It does look pre-WW2.
