I was thinking you may have had an older dog eared prop that came on the 4cyl motors of the era but that one does have some cupping but the rake is pretty tame.
The pic is of a Turning Point Hustler, a good priced AL prop that has all the SS features, substantial cupping, aggressive rake and hub venting. The rake is so that I had to alter the trim tab anode with a belt sander LOL. It's a 19p on my SS with the 115HP, the Chief I have a Quicksilver Black Diamond but it's like a 23 or 24p.
