Here is a list of possible answers that others have given (from this
board and others) for the chrome object with the clamp, maybe it will
spark an idea with someone.

-meat grinder/mincer (this one was suggested most)
-bottle holder for a boat
-garland holder
-drink holder
-tableside ice bucket base
-flower holder, clamps onto a casket
-tool that silversmiths use for making candle holders
-base for a tabletop carbonating machine
-used for hanging large banners from tables


I think that's all of them, hopefully I didn't forget any.
