This cabinet has been in our family since the 1960s. I have never seen anything similar. But it is an antique bakery case with original glass.!!! It is solid hardwood , but I don't know the type of wood. It has glass shelves and they are adjustable.It has small round air holes above the doors.
It has a door that opens and locks on either side. For easy access.
I have used it as a display case for collectibles since I've had it.
It is a unique item!!!
There are several coats of paint on it. But I would suggest stripping it down to its natural wood which is a lovely color.
