Sensenich Wood Prop Question

[[email protected]]

Can someone tell me what the difference is between a "CK" and a "C"
designation on a Sensenich prop? I am looking at a used prop for my
Aeronca Champ which currently has a W72CK-44 cruise prop. The used
propeller that's for sale is a W72C-42. I have a C-65-8 taper shaft--
will the C work on my engine?

Thanks,

- Brett

Hmmm... a C-65-8?
I know what an A65-8 is, and a C-85 and a C-90.
