At the purchase the original driving mirror was replaced by a normal traction mirror.

After long searches in the french bourses without positive results, the mirror clamp and the small arm connecting the clamp to the existing mirror support have been refabricated. 

The clamp should be made by using flexible steel material but the cut and bending of this material is very difficoult so that normal steel material (thk 1 mm) was employed.
The proper size and dimensions of clamp and arm were taken from a 7A still having the original mirror.
