Thank you for your reply Dave. Photo #5 is a pic of the underneath of the seat. A little background...I purchased these chairs in 1978 at an antique auction. They were "old" then, with terribly soiled rush on every seat. Since I actually wanted to use them, I had the seats re-rushed. I realize that hurts the value, but I really wanted to use them; I didn't purchase purely for an investment. I was recently told that they are early 20th century, probably prior to 1950. Trust me, the wood in places on each chair shows some age, but they have, in general, been taken good care of. Values for this type of chair are all over the place, so just looking for a little more info! Thank you again!
