The story about this lens is kind amazing, because I was just starting to work with DSLR’s cameras and I search for high class old Russian lens and I found in eBay this lens, but in that exactly moment I remember one zenit old camera that is from my grandfather, I ask him about that camera and he told me, wait a moment and he goes inside him room and came back with a SLR old Zenit made in russia camera, and that was amazing because that camera had this lens.
