Best Begins display I've seen. And I've always admired your closet. Mine is so sub par in comparison. But, I am starting to do some refit on it. Would love to know where/how you got the design for the gear mechanism for the insides. I once sent me a message about the modello on the front. Still, stunning after all these years. Hope you are still very proud of it!
The only reference I have are these screenshots taken from a "virtual tour" of the cave, the source of which is still unknown to me. You can sort of see how the handles would move the posts and "unlock" the doors. Other than that, just my own trial & error design.
Still not sure what that pizza-looking wooden medallion is on the right side door. Also it's pretty incredible how different this staged promo shot is for the film (my original inspiration):
from the 'real thing':
Lighting and angle is almost everything.
