Very nice early style NSKK motorcycle crash helmet. Eagle plate has cool yellow patina that only nickel seems to get. Nice piece of insignia. The helmet itself is complete. Leather is strong but could benefit from leather conditioner but there is no hurry on that and I prefer to let the long term owner do such treatment. One side ear cover does show some scuffing. Liner is size 58 and complete/undamaged. Front tongue is maker marked Hans Sch- . Nice, scarce helmet.
