Age of Table?

Question:I just purchased an antique looking table and six side chairs. The slide under the table is stamped Watertown Slide. A piece of paper stapled under the table lists the Niemann Table Co., Chicago. I know the slide was manufactured seperately from the table. Can anyone help me date the table and/or find a value?

Answers:
ill say count the rings on the bottem of a foot on one of the chairs, itll take along time but it will tell you the age.
