This run got me interested in this prop so I went back and watched all the x-wing scenes in ANH and ESB and it looks like there are 2 different configurations. Version 1 is used in all scenes in ANH and again in all scenes in Empire except for one. Version 2 is seen exclusively in the scene in Empire when Luke gets out of the cockpit when he arrives at Dagobah (when he’s dealing with R2 falling into the swamp). Oddly, v1 is shown again when he gets back into the cockpit to leave Dagobah (when he’s talking to Yoda and Obi-wan’s ghost).
Does everyone else already know this?
