antique?

[cornerstoretabs]

hey guys, my wife inherited this piece from her grandfather who passed about 2 years ago. We just started trying to research it. There are no markings on it anywhere that i can find. I found the term bubble/ruffle on a few other sites, but I'm not sure if this pertains to this piece. Does anyone know the proper name of this piece, or have any other information on it that can get me a better understanding of exactly what this thing is. I have checked a few other sites, but nothing really seems to come about. Any information helps.
Thanks
Chris
