I wonder if he just destroyed a valuable antique sewing machine. 
Not necessarily. I've seen plenty of those sewing machine bases that were in pretty rough shape. Not only that, but if the actual "sewing machine" was gone, replacing it could get ridiculously expensive.
And finally, often times the value in antiques like that is their being left relatively untouched. If the thing was in such bad shape that it'd need a lot of restoration, then the value could drop dramatically as well.
Looks pretty nice to me, though, as I recall those machines are a bit taller than a typical cocktail, which could make the viewing angle not so good. Hard to tell from the pics.
