I'm trying to find the origin of my great grandmother's curio cabinet that I now have. I'm guessing she would have had it in the mid to late 1800. It has 5 shelves, 2 sides have rounded glass, the door is glass and the front feet are lions feet. I have the original key but there are no markings to give me any clues. It stands about 5 ft and looks to be made of oak.
