Can anyone identify this very tall, shallow antique cabinet with dozens of notched, ventilated shelves?
I bought this unusual wooden cabinet at an antique store today and would love to figure out what it was originally made to hold.
It is approximately 70 inches tall and has two compartments with glass doors. It is extremely shallow.
Some details that seem important:
Interior shelf dimensions are approximately 12.25” wide × 5.75” deep.
There are dozens of fixed wooden shelves from top to bottom.
There is only about 1.6” of vertical clearance between shelves.
Every shelf has the same semicircular notch at the front right, approximately 1.25” in diameter.
The glass doors are deliberately narrower than the cabinet opening. When closed, they leave roughly a 2” vertical strip open along the right side, exactly where the shelf notches are located.
There are rows of small holes drilled through the left side of the cabinet between the shelves, apparently for ventilation.
The shelves are definitely fixed; they are not removable trays or drawers.
The wood is stamped “3455 G 3” on the side. There are also some other small factory-looking marks.
The construction, notches, ventilation holes, and narrow doors all appear original rather than later modifications.
The combination of the very shallow shelves, ventilation holes, semicircular notches, and permanently open strip beside the glass doors makes me think this was purpose-built for something quite specific.
Does anyone recognize what this type of cabinet is called, what it originally held, or who might have manufactured it? I’d especially love to know the purpose of the shelf notches and why the doors intentionally leave that vertical opening uncovered.
Any ideas on its approximate age would also be greatly appreciated.

I found this little squeegee to be a much better straightener than the suggested tool.

I remember buying it new around 1990, but I thought it was long gone. And yet here it is, but with no band. I need to buy a battery.
