Actually what you see there is nothing special, but the prop makes it look so - it is a standard 2" Al spinner. The prop is a 8.2 x 11 D speed prop with deep cuffed blades. So together they make a fairly intimate package, but only good for fat 2" diameter nose rings like the Demon.
But.. I recently picked up a pair of official OPS .60/.65/.67 speed spinner assemblies. They look really nice, and they are much smaller (40mm IIRC). Same thing you see on the nose of the VAE .60.
