ahh... we have one that is similar - has a know it the place where yours has the loop and a glass top - we used it for our wedding ceremony.. which is why your caught my eye sitting there...
This one has a small glass cup that fits in that middle small hoop to hold a candle. We inherited it from a friend of my Mother-in-law but I really have no idea of how old it is or what it's history is. She also left us her father's Gilbert American Flyer train set in the original boxes...
