^Good point, but if i'm not mistaken B&M split off from Intamin and Giovonola is B&M's subcontractor just like Consign AG. Also seeming that Intamin is much more experimental and adventerous than B&M, so how could they be Intamin's former engineers, also think about it Werner Stengal is a designer for both companies.
P.S. this message not to be taken offensively, I got this info from a book.
,well most of it at least.
