I have noticed that there are serial interviews with the staff behind this model on the September and October issues of Model Graphix.
Some points of interests were:
-The staff used the photos taken inside the ILM model workshop and purchased all the model kits that were spotted in the shelves.
-This made it possible for them to source and reproduce every single decal which was applied to the filming miniature; all except one which was applied in a place not visible from the outside.
-A few decals had to be slightly modified from the original because they contained trademarks, although they tried their best to retain the looks of the original.
-The model is based on the filming miniature in the state which was photographed immediately after its completion for publicity (before the filming of ANH?), after which parts started to fall off and some where wrongly reattached or newly applied.
-Some detailing parts which were not present in the filming miniature's primary state were spotted in photos which were taken right after ILM moved to a new studio for production of the ESB, but those were intentionally omitted from the perfect grade model.
-Landing gears were not made for the 5foot model and were thus based on the execution drawings of the life sized filming set.
-Every detail on the model is sourced; none were applied for the sake of filling unclear areas.
