Anyone familiar with Gibbard furniture?

I purchased this table at a yard sale because I just loved it. The table is apparently made by Gibbard (metal stamp on the inside of the drawer) and is solid wood. I know that the company made furniture for 173 years. I was wondering if there was any way to identify when (approx.) this table was made? identifying markings, etc.
Just to satisfy my curiosity

Any info would be a big help!

 

You may already know that this is (I believe) what's called a wine table, Georgian, I think. I don't know how to date it, but the furniture brainiacs will soon be along!

 

Given the labels inside, it's 20th century - what part, I don't know for sure.

 

Hi,
Those screws were not round before the 1960s.

For around a decade before the Bicentennial, they made a lot of Colonial design furniture. You couldn't touch a similar piece in a furniture store now; solid mahogany would cost a small fortune. It's a pretty sweet piece.
