Yes, you can often identify the engine used (or at least exclude common engines that were not used) by the hub dimensions, since the hub was basically designed to fit that engine.

Unless the design number corresponds to a specific aircraft or the aircraft type is stamped on the hub (more common with British propellers) then you can only really guess at what airplane it might have been intended for, and it may have been fitted to several possibilities.
