Prop Shaft

[gn7]

Do you have a pic of that?

Yeah I've seen them. I believe the use of 7/8 shafts may have started that way and evolved to include the prop itself, of for no other reason than prop availability. I imagine the grinding of the shaft was a pricey affair as well, but did make the prop hunt a little easier, and a little easier to dump unwanted/unused props.
