CKL66 no decal M42 helmet

Textbook late war produced M42 ND (No Decal) helmet. The helmet is nicely marked CKL66 which indicates shell size 66 and production by Eisenhuttenwerke Thale. The M42 ND is complete with its factory installed liner which still retains the drawstring. The inside of the helmet features the name Kupka. The front of the helmet shows traces of writing which was removed and cleaned. Nice late war ND M42 helmet in a rather large size!
