I have a friend who has a 1950's klipschorn, but he's not sure if it's a kit or if it's an actual Klipschorn. It's got a wooden squaker (Hope I spelled it right). It's got almost everything original. the only thing that's not is some speaker cable. He bought it 20 years ago. He's also got about 94 pages of plans or blue prints of the Klipschorn with a date of 1951 on the plans and then a stamped date of March 24, 1954 on them. I've got pictures if anyone knows what they are work or is interested.
