unidentified truncated propeller

[biggles2000]

Got this propeller hub from my father in law - he had it for as long as I could remember. Any idees. The hole is about 3" in diameter
On the front there are the numbers/letters G611 N64.
On the edge 545 HP and SPPX
On the oter edge 257 580 (these are all best guess!)

Looks like a British manufactured auxilliary prop of some kind.

thanks for the feedback Dave - where can I go to find out more? Just put it on ebay with a starting prcie of £50.

You'll probably find out everything you need to know by putting it on eBay.

The numbers G611 N64 are British and indicate a batch of 100 props made around late 1917. The batches before this were for the SE5A aircraft, so 545 might be SE5.

With kind regards,
