I contacted one of the most famous American sites dealing with WW2 to submit the photos of the article.
All the expert members validated the authenticity and gave an estimate of 800 dollars
For information :
Hermann POTTHOFF (HPC) COESFELD frischluft
The HPC visors were characterized by a special closable ventilation system, the so-called “frischluft” (D.R.G.M. 1419757), by means of a variable quantity of front holes with grommets (from 4 to 6). The inner circumference had the “stirndruckfrei” system too.
The HPC patent was surely used by the WILHELM MULLER house of BERLIN-KLADOW.
The color looks like the NVA's stone grey rather than the Third Reich era's field grey (feld grau).
