I am posting the pictures of what I believe to be a 1930s Jacobean Lifetime Furniture Dining Set. I found Sekmet's posting for their similar table and chairs and nearly fell out of my seat!
My uncle purchased the set for my aunt years ago with the intention of refinishing it. However, they were too afraid to tackle all the moulding, so it sat OUTSIDE for years in the Utah desert.
My mother and I refinished the table and chairs in 2003. Needless to say, my Aunt is very jealous whenever she visits.
My table has a leaf that folds out of the middle and spindles that hang from the skirt in middle of the table (men can only sit at the head of the table). But the carving and mouldings are exactly the same as yours. However, I had to chisel out the moulding on the bottom of the legs because so much was missing. My top does have a veneer on it, but it's not the same as yours. Mine has a more of a tiger's stripe to it. There is a ring on one end of my table that I pull to separate the table top. As I pull my end, the other end pushed out. So expanding or contracting the table top is a one person job.
Have you found any new info on the exact time period? After what I've found, I don't think our tables are part of the 1913 Jacobean line. I read that line still looks like heavy mission period with a few arches and some spindles.
I can't tell you how excited I was to find your table and chairs on here! I had no idea what the arm chairs looked like. I have four chairs and a strange stool. It's breaking my heart, but sadly I'm needing to combine two households soon. I am trying to figure out what kind of price I should put on the set.
