Hi can anyone tell me anything about this pine propeller?

All that I can tell you about it is that it is made of solid pine and it is about 49 1/2 inches long. The hub has only 4 holes as can be seen in the pictures. There are no serial numbers on it anywhere.

Here is a close up of the hub

It's almost certainly not an aircraft propeller.

Yes. I believe it may be from a military drone, thanks.

Most military drone propellers would have contract numbers or design numbers stamped on it, and likely would not be made of pine. I think it's more like non-aviation, maybe some kind of industrial use such as a fan or some other form of air movement.
