This is a vintage drop leaf dining table. Also called a gate leg table.
It is made of solid (maple?) wood, is NOT warped, is sturdy, and is in good working condition.
The finish is marred and has worn off in many places.
It is very heavy and does not have casters - so it needs two people to move.
The table is 29 inches high.
Extended with both drop leaves up and two additional leaves inserted it is 104.5 inches long and 42" wide.
Fully collapsed with both drop leaves down the table top is 26.5 inches by 42 inches.
The drop leaves are each 20.25 inches by 42 inches.
The separate leaves are each 19 inches by 42 inches.
The table has 10 legs - some of which swing out to support the drop leaves when they are opened.
I acquired the table in used condition approximately 50 years ago.
Since then it has been kept in our house and mostly used for holiday gatherings.
Over the last few years my wife has been using it as a sewing table,
but now prefers to use a smaller, easier to move table.
Currently we are storing this drop leaf table and the additional leaves in our garage.
