As you don't seem to believe that this kit was ever fitted, here is part of a photo I have of an RAF HC2 Chinook cockpit (the left hand pilot's bit): I have pasted (lower right) an image (from manufacturers material) of an RDU (Remote Display Unit) of the kit in question highlighted with some text; I have also highlighted with text an actual display on the console - I'll leave it to you to decide if they are the same display.
