These are super cool, and very versatile helmet liners made for the Greek Army, and never assembled or used. These are JUST the liners, and you can choose between the holes for the WW2 Riddel style holes already drilled, or not drilled yet, but there are guides for hole placement.
These are all unissued, but some have storage wear. Colors vary slightly, but most are similar to what you see in the stock photo. These are AWESOME for kids and for costumes or making replica WW2 M1 liners. Made of a heavy plastic, these are a SUPER cool and affordable piece of military history.
