The Olympus OM-10 is. This is possibly the cleanest example Ive had the pleasure to trade, being sold in virtually un-marked condition, fully tested & working perfectly with fresh seals, no scuffs, dents, scratches, lens is mint showing virtually no signs of use, no haze, no separation, no fungus, few tiny dust spots (normal and does not effect quality) unmarked mount, lens cap is mint, strap showing light signs of age.
