MCM Dining Table/Coffee Table Combination with 8 legs?  

I don't have a picture, as I just lent it to a friend who was in need of a dining table. But I picked up a solid wood table from an estate sale that has 8 legs that fold underneath it: four that make it dining table-height, and four that make it coffee table-height. I've never seen anything like it, and I can't find a think about it online. Has anyone seen these? I called my antiques friend and he said he's only seen one, many years ago, but that he can't remember the designer.
Any thoughts would be greatly appreciated!
