The wiz-wheel for SH4 would be nice, specially for S-Boats, since it serves both as target data tool and angle solver. However, note that it has actually TWO rotational wheels in the back besides the fixed background, and I'm not sure if they can be operated without reseting the tool when you move the second
The banjo would suffer the same problem :hmm:
P.S. did you all know that german attack scopes had an integrated banjo in a second ocular?
Moveable scales in various colours could be dragged and rotated through handwheels to display the firing triangle through that ocular, and the captain could alternate between target and triangle view while looking through the scope just by opening or closing his left or right eye
