Paul,
Thanks for the interest. It's the pear kit with extra details, especially in the lowest two decks. I am modifying those little details, like making the sliding doors/windows fully functional. This means adding things like the extra "Z" bracing, which I think may have been necessary to hold a sliding door together. Below are some photos, showing:
1) Boudriot's drawing - 8 being the door I'm working on.
2) The kit standard fixed piece from Signet's build which is awesome but I don't believe it functions. Signet can chime in if he made them movable. they obviously follow the photo from Boudriot's drawing.
3) My modifications start by making a hollow frame, which I slide the below door into. It hangs on a rider along the top of the frame.
4. Finally, the final product both shut/open.
Only reasons for the modifications are: To make the build last a little longer, add my interpretation of what certain details may have looked like and because it's fun.
