Help Identify Wooden Propeller

[stewart]

Please help identify propeller, found on L.I., New York, Roosevelt Field in an old abandon hanger in the 1960's.
Wooden propeller measures 8'+ long believed be mahogany. There are six bolt holes which measure 1/2" diameter. Center to Center big center hub hole is 3". Diameter of hub hole is 2 1/8 inch.
There are no signs at all of any serial numbers or indications of any metal or any other type material being used on wing tips or around hub, no seals of any manufacturers.

Six bolt holes are unusual for an 8 foot propeller. Most of the early props used hubs with 8 bolt holes.

It's possible it's not even an aircraft propeller.

It sure looks like an aircraft propeller? Homemade, maybe?

[Dave]

Well, I have no idea what it looks like, and lots of propellers look like lots of other propellers.

I also have no idea what you mean by "Center to Center big center hub hole is 3". Diameter of hub hole is 2 1/8 inch." Center to center implies two holes whose centers are 3 inches apart.

We'll definitely need more information, and maybe a picture.

Pictures would help lots. I doubt it's home made; I wouldn't fly behind a home made prop, would you? Six bolt holes in an 8 foot prop makes me wonder too if it's maybe not something besides an aircraft prop.

Here are some pictures. Thanks

Does anyone recognize this prop?

[Dave]

I certainly don't recognize it. The six bolt hole hub is quite unusual for that style of propeller (most had eight), and I can't tell from the pictures but it looks like it might be a left hand rotation rather than right hand, which is also not as common.

Also, typically you would find some numbers stamped on the hub, although often that doesn't even lead to a positive identification.

Anyone have an idea of it's age?
