Hello all - - -   just one more-maybe-re:the term "Eisenglass" - - when I first saw that post by here, I broke into song....... does anyone remeber that piece in the musical "Oklahoma"?  ".... when I take you out in the surrey with the fringe on top.... with eisenglass windows you can close right down" (paraphrased)
    Of course then my dogs had to come running as I sang, thought there was a sick cow or something!!!

Happy trails - -
