Nice pics Chaim, thanks. I agree, there was probably a lot of d-rings on hand at the prop shop, certainly plenty used in the movies but it's clear the prop guys had a predisposition to camera accessories since there was Kolbolds, MPPs and Graflex featured in the film. I would guess they used what they had, then sought out more d-rings and clips/attachments as needed. As far as the clip in ANH, once it failed to stay secure, they picked up another handy flash part off the Kolbold. May not have been the first choice, but it was used all the same. Whether they used the same d-ring is debatable, but again, why not use what you had sitting in front of you?
