It certainly looks consistent with WW1 era construction and material, although that can't be verified. It also looks like a LH thread, which usually (but not always) indicates a pusher application. I agree with the witness marks.

I think the best you can do is go to this page and see if the hub dimensions match closely to any of the known hub sizes of WW1 era props.

I don't know what's going on with that little rectangular inlay, but can only assume that it was an attempt to fill a defect of some kind.
