A very nice and hard to come by very large 68cm produced helmet marked "hkp" for the firm of Sächsische Emaillier und Stanzwerke A.G.  Helmet is in overall average condition and retains about 45% of the eagle decal.  Standard storage age and combat wear.  A good example that comes straight from the estate of the family whose veteran member returned from World War II with this as his souvenir.
