Jupiter-9 85mm f/2 M39 SLR №6503305 for Zenith-3

The lens is fully serviced in my workshop. Glasses are washed with Zeiss cleaner. The lubricant in the helicoid is replaced with a modern one. I didn’t bother removing any remaining lacquer on the barrel to make the lens look really vintage, not new. There are invisible cleaning marks on the front glass. There is some infinity overrun when installed on the M42, it may also work for Nikon.
