Duncan Phyfe table or reproduction?

I purchased this table at a Habitat for Humanity & I'm trying to sell it. A lady called it a Duncan Phyfe when she was requesting a price & after doing some reasearch I’m not exactly sure what I have here. I’m leaning towards a no but I want to be sure before I try selling it. Obviously it needs some TLC.  It does have a leave to extend the table out as well that goes in the middle of the table. If I could get an answer to what it may be & an estimated price on it I would greatly appreciate it!

The dimensions are approximately-

66” Long x 42” Wide x 29” High
