Sorry for not being clear (seems to be the story of my life when it comes to photography). I know what they look like (as I said, all my old Minolta gear, bought before 1989, had it). But my Pentax
dSLR gear does not. K10D, K100D, 18-55mm AL-II, 55-300mm and FA31LTD, they don't have it.
But I understand from your reply that an independent body checked every exported camera and lens up till about 1989. After that not anymore and that's why I don't have those stickers on my dSLR Pentax gear. So I do not have to worry about that any longer
Thanks for the reply.
