Yeah like I've been scouring the net for Robotron dimensions. For the control panel I had the overlay art and used calipers to verify measurements and I had bought the metal control panel blank but I decided I wanted to make one out of wood. I was literally pulling in snaps of control panel restores and then I knew the dimensions of the joystick holes so I used that knowledge to size the photos to measure the dust plate cutout and other dimensions. A lot of times it would end up being so close to a measurement I could tell oh they probably used 3" or 2.5" here.
