Thanks, John, because I also recently discovered that there was a K____R serial id for the Super Js.
I'm taking for granted that the serial ids were in alphabetical order according to age: K____N, K____P, K____R, and K___S (there may have been others). In that case, the fire would have happened during the production of the last--or one of the last series of Super Js. Is that correct?
Jimmy, what did you mean by "nose" in reply #6?
