     Isn't a word of caution in order, since not all TO-92 transistors
     the same order of B/C/E pins?

    Yes, I think there is supposed to be a TO-92A, TO-92B, and TO-92C (the
   different orders) but nobody paid enough attention, and I'm not sure if
   this is standard, or merely convention. see attached gif that was
