Is my junkshop find a Camfield propeller?

[April]

Hello! I found this beauty many years ago in a junk store. I know nothing about about her, other than it took three men to move her.

From my research the closest I have found similar are the Camfield propellers, but the one in the photo below is not an exact match. The wooden bases taper in more narrowly on mine.

I would love to know what type of plane my propeller would have graced, and during which era. Thank you for any guidance.

The taper/width of the blades at the root end on all blades is for engine cooling. i.e. an air cooled radial engine requires more cooling air at the root to go over the cylinders, than a water cooled engine with radiators in a different location. So if your blades have less blade at the root it could be for an engine not needing as much cooling. There would be a specific propeller/test club for each engine model/series.

I think this prop was a test club

Measure the internal diameter of the bore of the hub. That will tell you what "spline" size it is, and that can be backtracked to the horsepower range of the engine the club was designed to test.

Looks more like an air boat propeller or something similar than it does anything that would go on an airplane.
