Shelf Queen

A (usually) antique item, such as a clock, radio, sewing machine, spinning wheel, tool,car parts, etc, that may or may not work, kept strictly as a display item. More often than not the item does not work but the owner has no intention of repairing it, it just sits there.
In Modeling: a unfinished model that sits in a shelf, either half build, waiting for a part, waiting for more info, unpainted, almost finished, not ready yet....., and the owner has the intention of finishing it... sometime.
