The conversion was done by us using a helicoid conversion kit from Funleader in HK.

Mechanics mint, like new.  Has been 6-bit coded.

Optics very good condition.  There are some fine very scratches on the front element. The lens originally had fungus inside also (a common issue with this formula it seems).  We cleaned the internal optics and neutralised the fungus using UV radiation dosages.  However, some of the fine coating mark damage from the fungus remains.  It can only be seen in extremely bright light while looking through the lens.

Aperture is clean, focus is smooth and accurate on film and digital. Comes with front  clip on 43mm Zeiss cap and rear cap.
