The basic item is professionally made. See the examples of the attention to detail on the inside. It's solid work that screams "factory made". Not only that, but the quality and attention to detail indicates it is not purely commercial. But the hood is a roughly done "field made" modification. I have no idea what it might be, but I'm pretty sure I saw a picture of a similar one in Borsarello's "European" book (I don't know where mine is right now).
