Can you ID this one?

[Viertel]

I'd like to ID the aircraft that my wooden propeller may have come from. It was manufactured by Supreme/Stone Propeller Company in Wichita, KS. It's approx. 70" in length and has metal edging. The center mouting hole is approx. 2 3/16" in diameter and it has 6 bolt holes. It has the following numbers stamped on it:

S65C-50
2350 RPM
HP65C-70
38520

Thank you for your help!

Unfortunately I have no design number information on this maker. All the info I have is on this web page: http://www.modernwoodenpropellers.com/StoneSupreme.htm
