I bought a fish tales from an auction a while ago that could very well be HUO. Dirty as heck with no wear. 6500 plays with no quarters dropped. The "Goodie bag" contents were in a manila envelope. This was with all the easily identifiable pinball parts. I have not seen it before and can't imagine what it would be for. I suspect its not a pinball part but wanted to check before I tossed it aside.
