Yoyojam ???

i saw this yoyo on eBay a while ago.
its supposingly a Yoyojam.

i'm guessing its some prototype for the 'legacy', build-in weight rings range of Yoyojam yoyos, i tried to search for it at eBay again and its gone, Taka probably bought it off the ebay, thus this photo.

Taka also includes a comparison photo of it and a Legacy, pretty much the same size but slightly larger.

maybe someone got info on this?

link to Taka's post about this.
