WW2 German ND M40 Helmet

Trades considered for original condition SSH39 and SSH40 helmets. This example is in exceptionally nice barn find condition. I can't make out maker, but there is a stamping present on rear inner skirt.

Based on vent hole shape this is likely a Quist factory helmet. Getting more difficult to find these in excellent condition and this example is priced to sell: Don't miss out!
