G'day Gents ....
Right ... the Bk117 main transmission is manufactured by Kawasaki and was jointly designed by MBB and Kawasaki Heavy industries.
The Intermediate (42 degree box) and the T/R (90 degree box) were lifted from the Bo105 series machines and are manufactured by ZF (ZandfabrikFreidrichafen) in Germany.
The Bo105 used either the ZF72 or the ZF112 main Xmsn depending on the model (and or the military?).
They are all Bulletproof! (providing of course you don't use too big a bullet!!).
Cheers .....
