Yes, everything works just fine, you can just see the buckle mechanism as the plastic cover has broken off. Chin strap still buckles and releases. Other than that, it's a solid Wz.2000 helmet in great shape. I couldn't sell it with the other Grade 1s, so it's my loss, your gain for something that can be fixed by painting it or covering it with duct tape.
