Aviation Partners to install spiral winglets on Falcon 50

Photo and story of Gulfstream II with spiroid winglets.

Aviation Partners gets Washington money to jumpstart installation of spiroid winglets on a Falcon 50.

That should get a few extra gawks on the ramp…
It might also give the old GII the “Most versatile wingtips” award… I’ve seen them with & without winglets, with tip tanks, and now this.
