Case XX Magician's Cheetah

[never too sharp]

Does anyone have any info on where I might find this beauty? I saw it on the W.R. Case website and fell in love. There are two versions: the first with MOP on the obverse and abalone on the reverse, and the second with the same materials, just reversed.

I scoured the usual suspects on the internet to no avail. Love those swing gaurds!
