it's a 320cm or 10foot 6inch propeller . can't find maufacturer . seriel nr . 53480 or 53460. also there is a nr. 306 or 308 near center hole. it's is in the Netherlands.
With very minimal edge protection and no tip protection at all that I can see, is it possible this isn't an aircraft prop at all but perhaps a reproduction designer item?
Unfortunately, lots of very different propellers with very different uses look the same. They're a little bit like tires in that respect. They all look similar but they really aren't.
