In our opinion there is no substitute for a slate table and would not pay anything for one. Places like craigslist are full of slate tables sometimes for prices not much more then this.
A friend (seriously) is looking at this table and I told him that I might be able to get it identified. The seller says it's a Brunswick.
These are all of the photo's that I can get.
i owned one of them yrs ago...also paid 100$ for it...you will never get it level,but...its good if the kids want to learn or do like i did...donate it to a youth group and let them enjoy the game
