What is WIW?
Flottorp did make certificated propellers. Generally they have
Model , length/ pitch/ Type Cert data stamped on prop.
Maybe the pic just doesn't show it.
I don’t recall “ Kinectics” though.
Perhaps it was custom made for Experimental.
Univair was a dealer for Flottorp.
If you have data stamped on prop I suggest you research their catalog or call
and determine application.
Once you know application and current price you may want to contact a type club
for the aircraft type.
No stamped data and it would be a Wall - hanger with a clock.
