Haha, I enjoyed reading that Dennis, I also do not think it is contagious, but I know there are a few who believe it will spread. I think that belief comes from collectors who noticed it happening to one piece, then another and so on... BUT had those pieces been in different locations it would have just as likely occurred. I also forgot to add Märklin to the list, I have a few dynamos with outer shells/cases that look like they'll explode into a million pieces if you even breathe on them wrong.
