German Soldiers frequently named or personalized their helmets. This ranged from simple naming on the leather with pen to naming in paint on the inner skirt close to the lot number stamping.
The paint was most often white, but red or black is occasionally encountered. The naming may have been done by helmet’s owner but was more likely was done by the platoon or company "artist" who named all the helmets in the unit in his own aesthetic way.
Other examples of personalization also exist, such as name tags sewn in the leather and sticker tags.
