Excellent overall condition, the top cap and cage show some stains but nothing serious. The case is in very good general condition, a small defect on a corner (shown in photo).
Be careful not to tighten the screw too much, to avoid forcing on the thread. This kind of long-studs cap is very rare!
The pictures show the right way to put the cage (yes, it’s not the way around!). The Famex mark should appear, when the razor is fully mounted).
