Very Long Narrow Antique Workbench

Antique (or possibly vintage) large old wooden workbench made in the 1920s probably, though it's difficult to tell which part of the first half of the 20th century really, or could even be late 1800s. It would make a fantastic kitchen island or café table. It's very long and narrow: the top is made out of one piece of timber; that probably indicates an older age. Not sure what timber as it's so gnarly and blackened but I don't think it's pine. It's very heavy but I tend toward beech rather than oak. It's really solid too: the legs have been cut into the top with massive tenon joints and there are full length stretchers below. I don't really want to sell this so it's expensive.
