NiteCore, 4Sevens, who licensed the McGizmo piston drive?

[ImGeo]

On this youtube video (4sevens' instructional video on the D10/SmartPD), 4sevens states that "we" licensed the piston drive from Don/McGizmo (or so I heard).

Which leaves me asking? Did 4sevens license it? Or did NiteCore license it? Or is 4sevens connected to NiteCore?

Nitecore, and 7777's is one of their representatives.

As far as I know anyway..............

I remember the smart PD series was collaboration between NC and 47.

This was covered on another forum, it is basically a private matter that from what I know was handled above board. The design was not patented so technically it was not licensed however an appropriate gentleman's agreement was reached.

Are you related to Handy? If not disregard my question.
