Contax Cine Conversion Gear - Delrin Focus Gear for Contax lenses. Large size

Description

These are like new, used Delrin focus gears for Contax lenses.  Most were made by Duclos lenses in Los Angeles.  A few were made by Cordvision.  They are identical in manufacturing tolerance and material.  There are two sizes.  One for all there small diameter lenses and one larger size for there larger diameter lenses.  Zeiss was very uniform in the manufacturing of these lenses and they all do match up!  This listing is for the large size.
I don't wish yo use my Contax lenses for video work any longer so these are going.  They are in pretty much new condition except for a few nicks here and there as you can see in the pictures.
Advantages:
-High quality, fully machined. Not low quality 3d printed or injection molded.
-Truly seamless 360 degree gear so it won’t get in the way of long focus pulls.
-Will fit the lens perfectly like the lens gears on actual cine lenses. Professional and simple.
-Shrink fitted to lens instead of sets screws that have the potential to cause damage to the lens.
-Truly round gear for smooth operation unlike many of the other available gears.
-Good abrasion resistance. Self lubricating properties.
