Dining table chairs and buffet set

Hello,

My wife and I just purchased a dining set, but the seller did not have very much information on the pieces. I searched and could not find any manufacturer name or date on any of the items. I am hoping someone can help us identify the time period at least. We are grateful for any responses. Please see pictures below.

I have more pictures, but they were too big to upload. Let me know if these are of inadequate detail/quality and I can try to upload the other pictures.
