Here the front of the rangefinder is marked Certo Dollina, Dresden 46.  This refers to the Kleinzschachwitz region to the east.  This designation appears only on early versions of the Dollina II that have the noticeably taller rangefinder  mounted on top of the body.  Subsequent versions having a slightly reduced profile are not marked with the Dresden 46.

The buttons located on the front rectangular assembly placed just above the door control the door latch and the frame counter. The frame counter had two functional controls, the sliding bar seen in the closed/locked position to the right on this assembly, and the round button immediately to its left which when unlocked ratchets the frame counter downward (two frames at a time - oddly) for resetting.

Of the two examples of this model that are in the collection, this one is more worn from the decades of use.  However, the shutter works well and the Cassar lens produces interesting images and it is a pleasure to carry in a coat pocket for a day of walking around old towns here in the middle of Italy.
