Two super clean adapters being sold together. The larger Kilfett adapter has the lift out filter holder which is smooth and clean as well as the ability to rotate in the mount. The Leica Leica CX 11080 C adapter shows a little more use but no abuse. One metal screw in tail cap is shared between the two adapters Both are clean and quite functional. I have several other clean Kilfett and Leica items listed, $150.00 plus $9.00 for shipping in the US. I'll ship for free in the US if you buy multiple items. Thanks for looking!
