I don't know if it was already posted before, but I found this very cool page on Lands of Lore with tons of item, armour, weapon, spell and monster statistics. Some of it taken from game manual (monsters) but I don't know what's the origin of the rest of the stuff. Can't find those tables in my book, but the font looks the same as in manual.
It's a spoiler, so beware.
Here's the link:
