It's almost certainly not from a wind machine and may be worth considerably more than a wind machine prop.

It's definitely worth pulling out and taking some photos of the whole prop, any stampings and decals if present. Feel free to email them to me (you have my email address already) and I can post them.

To answer your question about pusher/tractor, reversing it doesn't do anything to the airflow. The pusher comes from mounting the engine "backwards" from its usual mounting. So a Liberty engine mounted in the front is a tractor and uses a right hand prop. Mounting that same engine on the rear requires a left hand prop and becomes a pusher.
