Looks like an upholstered version of these chairs, which are not MCM. Your chairs don't look MCM or like Dunbar. The construction and style is very basic when compare to Dunbar. What makes you think they are Dunbar? Seems like run of the mill early/mid 20th century victorian revival to me. Good Luck.
