Straight from the estate of a well-known military antique collector which includes over 30 helmets and pickelhaubes from pre-WW1 and WW2 era that will be listed on my page in the near future (pictures available upon request). Anything mentioned herein is simply my uneducated opinion. This particular helmet is in phenomenal condition for its age showing no signs of major trauma or damage and is structurally sound and straight. The leather exterior is beautiful with no tears or holes and very minimal crazing.
The chinstrap shows age but is still intact and in good shape. The inner liner is time-capsule preserved and shows very little signs of degradation. "54" stamped under the liner and under the back bill. The included transport case shows obvious wear from age. The buckle is missing and both leather straps have disintegrated and are not fully intact anymore. The interior cloth is still fully intact but has some spots of discoloration. Stamp under the liner is faded but appears to read as follows. This does not appear to be a reproduction but its authenticity cannot be guaranteed. Stand seen in pictures not included.
