I was joking of course Vance :-)
It is beautiful is it not?

Note how the spinner is streamlined around the blade roots
at top speed. (With cuffs)

IIRC, this is P3 Orion turboprop blades cut down for the
Rare Bear, altho the P3 has square tips (I think).

Roncz's racing prop had square tips (constant chord) and
tapered in thickess to a knife-edged tip.  All aluminum.
(On the Pond Racer, I saw it up close one day).  The
engine pods were the proverbial 5 lbs in a 1 lb container.
