Could you send me (pmdecombeix at yahoo dot com) some "very large" and clear pics of the four sides of the hub ? If the central hole on the side not shown on the pics is not "flared", it is probably a pusher prop, and then perhaps for dirigible.
The shape is very like Ratmanoff propellers, except for the "bumps" of the blade feet.
