Yes Serial number imprinted on back 29P201 & 2
They are birch they came to me raw wood I have rubbed Linseed oil on them. I will open back cover and look at magnets tomorrow. One of the tweeters went out in 1989ish. A friend of mine took them to the Klipsch factory in Hope Ar. in the early '90's, before Klipsch moved. They were repaired/reworked in the factory then. They still sound great being pushed by an old Marantz amp. Cosmetically they look rough, but ok for my garage.
