Thanks for the response, but I'm still not getting it. Here's another image I edited with labels on the levers and axels for clarity.
So, if you start a climb, pressure inside the instrument case will be higher than that of the bellows causing them to collapse which pulls lever "A" down. With lever "A" being pulled down we can assume that Axel "B" rotates counter-clockwise (as viewed from the front of the instrument). If axel "B" rotates CCW then the teeth rotate axel "C" Clockwise which gives the VSI a "down" indication.
Am I going crazy?
