Unearthed from my father's warehouse, whose hobby was camera repair. Russian-made Jupiter-9 85mm F2 Made in 1966, Factory: LZOS (Lytkarino Optical Glass Factory) This lens is a Jupiter-9 85mm f2 Leica L mount (L39) lens, and the first two digits "62" of the serial number "N6201707" indicate the year of manufacture, meaning it was made in 1962. The above is the result of AI assessment. I am a novice when it comes to cameras. I have no knowledge. The photos are everything. Please take a good look at the photos until the end.
