You see it all the time on camera gear... that little, reassuring adhesive that let's you know that the camera, lens or camera gear was inspected by... uh... someone somewhere. But who? Where? When? As it turns out, this oval PASSED sticker was affixed to virtually all camera equipment exported from Japan between the 1950s to the mid-1980s.
All following quotations were obtained from Savazzi.net
JCII stands for Japan Camera Industry Institute, and JMDC for Japan Machinery Design Center. These stickers were attached to camera products that satisfied minimal quality requirements and were not blatant copies of German camera products of the time. The sticker does not mean that the individual item was tested, only that its model had been deemed to be usable and not a knockoff. At that time, goods manufactured in Japan were regarded abroad, often with good reason, as cheap trash or (externally at least) exact copies of patented items made in other countries, and this sticker was an effort by Japanese companies and government to improve their image.
So it's a bit of a shame that these official looking little bastards don't even denote any sort of quality check, however, there is a strong perception that they do. So much so that people have begun to falsify them.
Today, some second-hand sellers seem to attribute an extra value of sorts to items carrying these stickers, and recently-produced fake stickers of this type are apparently available. There are even reports of JCII stickers seen attached to second-hand cameras and lenses made in the Soviet Union, China or East Germany, which cannot possibly have been exported from Japan. As explained above, there is no intrinsic value in these stickers, either real or fake.
Well, I hate to be the bearer of bad news, but next time you see that little, gold badge, you can at least rest easy that it's not a German fake, or maybe you can't, because maybe the sticker is a fake. I still rather my gear have it than not. Makes me feel good inside.
