Mechanical Tea Cabinet, Trick Tea Cabinet, Cabinet, Tea Cabinet, Display Shelf, Tea Shelf

I am currently decluttering my parents' home ☺︎

This is a tea cabinet that was my father's favorite, as he loved woodworking crafts. He would often proudly talk about the cabinet's hidden mechanisms, even though he didn't create them himself.

Height: approx. 88.3 cm
Width: approx. 90 cm
Depth: approx. 37 cm
Please note that these are amateur measurements, so there may be some slight errors.

Behind the sliding door on the lower left, there is a hidden drawer. (Photos 8 and 9)

On the lower right, there are three drawers. If you pull out the very bottom drawer completely, there is a lid that opens to reveal a storage space. (Photos 6 and 7)
Also, the second drawer cannot be pulled out unless the very bottom drawer is slightly extended.

The mechanisms I was told about by my father are as described above. Therefore, I cannot provide support for any issues arising from a lack of explanation if there are other hidden mechanisms. Please understand.

Regarding the glass on the upper sliding doors, it reflects and shows the surroundings, so I have taken photos from an overhead angle.
The glass is dirty, but I do not see any cracks or chips.

Please make your decision based on the description and photos. Thank you to those who understand and are willing to proceed.
