Can anyone provide any information on a Brunswick Viscount?

I'm looking to buy a used 8ft Brunswick table, model is "Viscount". it's a 3 x piece slate. Tops look flat, but one piece of slate is uneven/chipped on a end - the opposite surface is perfectly flat so I assume the uneven piece won't matter if it's on the bottom. Is this ok? or is this a signal to stay away from this used table.

I'm a newbie looking for suggestions
