Original SPH4A helmet, belongs to US ARMY, and most likely Mohawk OV-1. Size large I believe, helmet is used and has a small crack below the visor rail... Otherwise complete to my knowledge and visor working ok. Please look at pictures, what you see is what you get. That being said, there are other options more economical, if flexible, please ask.
