Lens kit.

Kill or cure time. Using an internet guide with an amount of interpretation, took the plunge and completely disassembled my charity shop "bargain". Focus wasn't working as the mechanism was caked with fossilised grease so cleaned and replaced (twice - first go used silicon grease which sounded good but too thick!) then many, many attempts to screw it all back together to get the focus setting right. A learning experience if nothing else! Now quite good at disassembling Zeiss lenses!
