Washburn I'll get some measurements. Anything in particular?
I've mostly been looking for Burke chairs, which are an easy search, as the name is molded into the bottom of the chair. I've searched for Madison chairs online with little luck. I've experimented with terms like "mid century modern " and never found anything on the Kirk chair.
These came to me by luck. I got a call from a guy I bought some Burke 115s and a table from. He didn't know the Burkes were Star Trek chairs before I told him. Him and his son deal in old furniture, estate sales and antique shows type thing. His son found these and his dad said to call me as I was a Star Trek guy. Luckily I could afford them right now. That's what I'm choosing to believe anyway.
These were waiting room seating for a long time apparently. They still have the chewing gum underneath to prove it! Some cleaning is due for them. The wood and metal trim is all in good shape though. And the upholstery is surprisingly good for its age. All the chairs are ink stamped 1966, some of the bases are also. That was a good year for sure.
