Quoted from Otaku:HUO '74 Williams Strato-Flite, all stapled papers intact and nice even inside of the body, all original interior plastics still on the coin door, which you never see (and in nice shape), cleanest game on the inside I have ever seen, it's crazy how different maintenance feels on this compared to the rest of my games based on how clean the inside is. Spotlessly clean inside of the head, and the inside of the body is clean too if not as spotless.
Original piece of paper with serial number on it still scotch taped inside of the head. Paid $100.
Sorry, but I don't believe this game is HUO judging by the photos.
