Thank you for submitting your item for appraisal. This appears to be an arts and crafts inspired walnut end or side table. The table consists of ten pre-fabricated parts, sawn out sets of four plus four for the legs, the table top and a central column. Such sets were available by mail order from a number of manufacturers since the early 20th century. The estimate is based on similar items actually sold at auction. There is no measurement for the sentimental value you might attach to the item.
