yeah we register our significant trademarks. We have both approved this design. Its a shutter but neither of us did the cad, merely the concept.

Why no bimetal shutter? dude just won worlds again without it. only 2 people have ever done it with a bimetal. why bother? it needed a point, it needed the story… again, its a story we will enjoy telling, but not today!
