Are these genuine O.D. Mobler chairs?  

I picked up a set of six of these chairs from a guy selling off old furniture from his dad's house. I don't know much about furniture but they are solid and well made. The wood appears to be teak and is in great shape although the upholstery is not. They all have silver stickers on the bottom of the cushions IDing them as O.D. Mobler however the google did not turn up any O.D. Mobler chairs with exactly this design. Does anyone have thoughts on if these are genuine? Thank you!
