Finding a blueprint

[terry]

Hope someone can point me in the right direction. I have an early wooden prop which was identified using this forum in 2006. Im trying to find out where I can get copies of the blue print for it. The following are the details on the hub:
Hub has 9 holes
G1731 N78
A L 7901 RH
200LHP SIDDELEY
2000
P 2000.

I understand it could be for either a Bristol F2B Fighter, or a DH9 Bomber?
Thanks
Terry

Blueprints for these seem to be basically "non-existant".

Again, thanks for getting back to me, I appreciate the time you have taken.
