Reworked the doors to be more accurate, scratch-built some new rosettes for the handles. Not the final stain on the handle arch, it will match more eventually. Not the final look for the large ring either, it will be carved accurately.
Also rotated the handles horizontally and installed a locking gear mechanism. Now the handles actually rotate into the vertical position which turns the gears and slides the locking posts down from the top. Not completely accurate, since the original had one vertical and one horizontal crossbar, but I couldn't do that because of the batarang hangers.
Inside, added an accurate cape to the display. Exact custom fabric used in film for "hero" closeups, made to correct pattern. Electrostatically flocked for maximum darkness.
