Flip Top Expandable Dining Table / Desk / Entry Table

I believe this is a Victorian reproduction manufactured in the 1960s or someone took impeccable care of it for over 100 years. It is an expandable dining table/desk with slides - made by the Watertown Table-Slide Company in Wisconsin - that help it smoothly convert from a desk or entry table to a "choose your own size" dining table. See photos and measurements below. The legs are beautiful ball and claw feet. It should have 2 drop-down legs when it is fully extended, but this table is missing one. It is mahogany veneer over solid wood. The base and dining table top has a high gloss finish. When it is closed to be a desk, it has an inlaid faux leather top. It could be real leather with a varnish finish, too. Not sure. Width: 39-1/2" Height: 29" Fully extended Length: 81" (3 leaves, 13" each) Intermediate Lengths: 68" (2 leaves) 55" (1 leaf) or 42" (no leaves, just flipped open) As a Desk or Entry Table: 21-1/2" D x 39" W - knee clearance 23-3/4" Some light wear can be found throughout and some light scratching and scuffing to the table legs and desk top. I only used it as a desk so the leaves and table top are in great shape. I can deliver if you come over to help me carry it down the stairs :)
