Can you please help me identify my kitchen table?

Hello,
I had purchased this table thirty years ago during Spoon River Drive in Illinois. We have used it as our kitchen table all these years, but I never knew anything about it, but always wanted to know more about it. Could someone help me identify the age and type of table it is? If possible, could anyone tell me where it might have been made. As you can see it has five large fluted legs. The table is very solid. There are wheels under each leg and they are made of wood. Also the glides under the table top to expand it for leafs are also made of wood. One side of the top of the table is warped and I am going to try to un-warp it. I thought I would use water and weights. If anyone has another idea how to do that, I would appreciate hearing from you.
Thank for any help you can give me.
Dennis
