Round extending dining room table, by Lentz

This is a medium-dark round pedestal table (about 48") with three leaves (about 9" each) that extends to about 75". The table slides open without need of moving the pedestal(s), since it has a single base. The table was manufactured by the Lentz Table Co. of Nashville, Mich., and sold by Lachman Bros of San Francisco. From what I can tell, Lentz may have close in the early '50s, and Lachman closed in the '70s. It's a beautiful table, but is in need of refinishing.
