For sale is Tamron Adaptall Adapter for Konica KR  Mount. It will fit only Tamron Adaptall lenses with interchangeable mounts.  I would rate it at 8 for the looks and 10 for performance on a scale of 10. Ring has been used, but it is very clean. It shows normal wear from use. Ring is in good condition, no major damage.
