There was a publication that was done circulated about the time WP bought KA, it was called something like the [ Inner secrets of Kitchean Dishwashers ]. I think it got posted here at some time and I have a printed copy of it somewhere, if it can't be found I will look for my copy and send it to Robert so he can properly pass it on to members that want it. It said that it was produced for internal circulation to WP employes to help aquatint them with the KA DW line and KAs history, it was by far the best document that I ever saw on the subject and it would be interesting for a few of us who are very experienced [ Stevet, Tom, my brother and I and a few others I can't remember now, sorry ]  with KA to update it.
