I would add a few more things:
At the Hengstler counter section, I'd not use the last 3 images as they are of screen used Sterlings from various auctions like Prop Store, but the E-11 parts were added later on. I would be wary on using those images for the greeblies, the screen used sold on auctions Sterlings should only be used for the blaster itself and not for the parts added on it later. In ANH the Hengstler counters were in various positions depending on how they were glued on, see images attached.
