Set of 6 chairs

Hi

I dont really have any information about these chairs other than that they are a set of 6 and 2 of them have arms, the rest dont.  They were being offered as a dining set on a Freecycle website, there wasnt a picture just a description saying solid wood table and chairs available.  I dont think the table matches as its round and I thought the 2 Carver chairs were meant to go at each end of a rectangular table?  Really well made, there are no nails or screws anywhere. 

Any thoughts of their value or information of make or anything would be great.

Thanks

Tracey
