I really want to have a bash at recreating the Rani's Com bracelet on Monday
It's such a great item. Studying the episode it looks like there were two versions used in production. A dummy version used in most shots, and a working hero version for one or two close ups. What to do though ? One version for a start has black blanking blocks on the strap, the other silver !! Recreating the dummy version will mean the replica wont look screen accurate when compared to the hero version, but the hero version looks absolutely naff when seen in close up !
