Where is spinner numbered on a max prop classic?

[Peregrine1983]

Hi all,

I had to change the pitch settings on my max prop classic, but can’t see for the life of me where the spinner is numbered to accept the correct blades. See photos.

If anyone knows which blades go on the half of the spinner with the grease ports, I could probably figure this out by process of elimination.

Thanks for any help!

Clean off the flats on the outside of the hub. The flats on your last two pictures.

That explains it! Thanks very much, stormalong.
