Does anyone have info on Warnke prop serial numbers?
i would like to know if the pitch can be identified from the serial number
I've searched the web to no avail. The prop is still mounted and may have identifying numbers under the spinner.
Warnke 99051147 air claw" is posted in engine log. Measured 68"dia.
Any help would be appreciated

A couple of us were located on the same airport as Bernie and tested his props in the late 80's/early 90's on a 180hp and 150hp RV-4 plus his own RV-3. I doubt there is any correlation to the serial number and the pitch. I don't recall any ID on the hub of my Warnke prop. I sold the plane many years ago but it is still at the same airport and I can check with the owner.

While Bernie was a master German craftsman and designer (think "Almost Constant Speed" trademark), I am not sure he was the best record keeper.
