Rotol R66 propeller

Hello,

I’m hoping someone could tell me what this propeller hub is from. Its a 4 blade Rotol R66/4B5/18. The books I have don’t have it in. Is it post war?

Thanks, Jamie.

Anneorac is a mystery to many of us – rather like the Stig of the propeller world. Some say she can calculate a gear ratio from engine note and blinking with each prop revolution. All we know is… the reference book doesn’t exist, it’s waiting for Anne to write it.

Thanks Anne! Do you mind me asking where you found this out? I’d be interested to know if its from a reference book.

Thanks, Jamie.

R66, that will be Firefly FR4 to AS6.
