Well, I must say its a style I am not familiar with !! Looking at the under side,, those edges look like pretty new cuts and some of the wood is not aged as the main parts are !! Can you put the chairs side by side and take a good square shot of the seat ?? I am trying to figure if they had a cushion or something else over the wood !! Would not have been used as is !! If I were to bet right now it looks like they were put together from other pieces of furniture !! I also noticed the small hole at the top of the chair back !! Wondered about that !! Legs are like Windsor types and constructed similar, back is rather strange and doesn`t seem to fit with the rest of it !!
