As explaining for me, this lens block can to cover even a medium format. In 1945, after the Second World War several dozen Sonnar 180 lens blocks, was gone in the Soviet Union as reparations. In USSR original lens block was insert in a new rim with M42 screw mount by unknown specialist (it seems on the optical factory). I have bought with m42 and correct FFD for M42. I do not know how this doing, but compensation lens not used. This rim absolutely not similar on rims what used on Jupiter-6/Jupiter 6-2
Weight of my version about 1,1kg

Very nice to have such rare optics with such a pedigree! Treasure it.
