OvertHawk: Thanks. From what I've been able to glean, the 'A MkII' was fitted with upgraded Allison 250's (I'm guessing a variant of the C30?).
What do you suppose that sheet of metal is riveted to the boom - some sort of strengthening? Still, not as ungainly as the piece of 'angle-iron' Agusta 'welds' onto their 109's and 139's!
NMH: I don't have any cabin shots of this craft but someone else may have.
