Torque/Power/RPM curves for Rotaries

Does anyone have the Torque/Power vs RPM curves for the Le Rhone, Clerget or Bentley. I am trying to work out the power bands on Rotaries.

Sorry for the delay, but you can see that I was occupied with the intellectual pursuits above.
The Wright-Pat museum has a booklet from 1919 that shows original curves and those of modified rotaries. It is under "cam modifications". As I remember, it is excerpted from SAE proceedings from 1919...(I did the research over 40 years ago and memories dim with the passage of time.)Contact the librarian/curator, who will explain how ;you can check this out by mail.
Actually, I may have a copy of this in my pile of literature, so if I find it I will get back to you.

Thanks John.
