Rodenstock XR Heligon 100mm F1.5 lense in a a decent shape with decent front optics but I can see a deep scratch on the rear element keep that in mind I can also see some dust specs micro hairline scratches and wipe marks. these are industrial lenses with a use for lab work, scientific work etc. Lens does show some wear.lens doesn’t have any focusing helicoid or iris. 

These days people are somehow adapting these high resolution lenses on Digital Mirrorless cameras but that needs lot of expertise and mechanical work.
