Well, it looks like one. I picked up an old pre electrical sewing machine table to use the cast iron legs for a table I'll be building. And this came with it. Its the cover for the old manual sewing machine that was missing from the table. The person who I got it from asked me if I wanted the "coffin" that used to cover the old sewing machine. I said sure! So here it is. Now im thinking of what I could stuff into it. Maybe a guitar amp head?
