Thank you for all your help! The consensus is they are replicas, Budman's reply and ebay web reference of Klipschorns look pretty much the same without the serial number tag but the insides are painted black. I don't want to labor the point, but looking for specifics--can you guys point the specifics out for me. Also, Munkiman--thank you for your response -- you referred to them as Speakerlab Ks K-Horns. I read online that Klipsch built Speakerlab -- do you know is that is true?
Again, thank you all!!
