Yeah, I'm kicking myself for not jumping on buying one of the (8) NOS backglasses Todd at TNT had. Right as I was getting into the hobby and reacquainted with my childhood memories of the HH game, I seen the youtube videos of him restoring Haunted Houses and mentioning he had these glasses. When I finally committed to the search of getting myself an HH, and realizing the rarity of the old glasses in that good of condition, I called him to see if he had any available and he said "the last one was shipped out yesterday". This was before I even owned the game, but I knew I wanted a pristine condition glass. I was a few days too late. Bummer. And what sucks is he was probably sitting on these glasses for years.
Fingers crossed for finding one soon. The one I have is a 7-8 out of 10. Overall nice, but has some flaking cracks. No paint is missing, you can just see a crack line or two when it's lighted up. But nothing noticeable from standing afar. If I would seal mine, the cracks would go flat again and you wouldn't even be able to spot them up close. But i'm not sold on sealing it yet since that will eventually break down and ruin my glass.
