Large turnscrew, rosewood handle

I didn't drive any screws with it, but I believe it does in fact turn! The handle is rosewood, and shank and ferrule are some flavor of steel. I refinished the handle with shellac and paste wax, and shined up the metal a bit. Only apology is there seem to be some light scratches on the metal, possibly from a previous "restorer's" wire wheel. Coming in at over 19", it's an impressive bit of kit or decor.
