Info needed to help with Whirlwind project

Can anyone out there confirm that the DH prop on the Westland Lysander has an exact ten foot diameter??

Cheers,

Matt

EDIT – It’s been pointed out that the Lysander and Whirlwind props rotate in different directions. Still, a pattern that can be measured, put into CAD and reversed is still of use. I know that there are other options, but I would like to cover all bases.
