IIt is an entire website dedicated to the Henschel and Porsche turret versions of the 1/16 Trumpeter King Tiger and nothing more . some of the worlds greatest modelers and historians post there.
just politely ask if anyone can scan the directions for you. It's really very simple
... I would send you mine but they only cover the Henschel turret as it is an early release before it was offered as 2 in 1.
good luck to you
