I have not done anything to the helmet but to wipe it off with a soft cloth. This helmet came home with a family member from WW2.
To me it looks to be in good shape for its age, i don't see any damage on it like dents, besides some paint missing, please see the pictures. Would make a great gift for a collector or a great edition to a collection. The item "WWII Antique German Helmet.
