We have tachometers and stopwatches.  RPM and MPH.  Cause and effect.

Not to ignore the all important scale.

Perhaps I was a bit too obtuse...

How about some prop numbers like Dia. and pitch @ 50% Dia.

I know what you mean.  Modern F2D props are sold without pitch & diameter numbers.  Just colors and the name of the user.  As in green Chorneys.

I guess somebody with a Kilsdonk pitch gauge could go into the business of aftermarket prop numbering.
