Default mystery prop ID needed

I just bought this prop

It is a wooden propeller,covered of an "olive drab" canvas.

the diameter is:64 cm.

On the steel plate the number is :09.6.1638

on a side of the hub ,there is a number too.It is difficult to read it.It seem to be: D 3687/51??/4/5 ?

I was thinking it may be some sort of ancillary for driving a generator ? any help you can give would be greatly appreciated.

It's some kind of air movement fan, and the hub and general design suggests a non-aircraft application, or possibly a test prop of some kind.

I think it will be very hard, if not impossible, to identify with respect to a specific machine.

Would you be able to make an educated guess at its age from its construction nearest decade would be a help.

I found this picture of a British airship generator prop from 1910 it seems to have a similar hub design ?

As I've told lots of people, finding a prop that resembles a prop is a little like finding an automobile tire that resembles another one. There are still hundreds of possibilities and no way to narrow it down without specific data, and unfortunately so much of the needed data just can't be found . . .

In addition, your prop is a right hand thread and the picture is a left hand thread.
