I'll send the height and a photo of the bottom side of the table later today or tomorrow.

Corrections: Banquet table has 6 legs. The 5 extensions measure 21 1/2" wide, plus there are 2 more extensions measuring 12" wide each. Also, here are photos of the underneath. The table stands 30" high.

Good morning, Margo,
Thanks so much for the corrected dimensions and the photos of the underside - they are tremendously helpful and confirmed my suspicions that this table was of late 19th century manufacture rather than 16th century.
Based on the photographs and information provided, and subject to examination, this is:

A Jacobean style or Renaissance Revival carved oak(?) extending dining or banquet table
In the English style, late 19th Century
with six heavily carved bulbous legs, the top with acanthus edge over a skirt with lunette and mask decoration.
30 inches high, 60 inches wide, 60 inches long (closed), with five 21-1/2 inch wide leaves for a maximum length of 191 1/2 inches
CONDITION: not examined in person but appears to be in good condition with wear commensurate with age and use.
PROVENANCE: Purchased from the Engineers Club in Baltimore in the 1940's by client's clients grandfather.
$800-1,200

Good Morning Delia,
Please tell me what it is about the underside that informs you of its age.

The expanding mechanism, where the supporting rails slide together and "stack" next to each other when the table is compressed, was invented in the mid-19th century. Earlier expanding tables would have had "fly-leaves" where the extensions are stored UNDER the top and attach to the ends of the table, rather than in the middle. Other ways to extend are to have additional pedestal supports or a rotating mechanism, which Robert Jupe patented in the early 19th century.
