Amazing job! I'll be using this to double check Mistipedia for anything missing... 
A few nitpicks:
Unhallowed 11/60: Van Richten
If I'm not mistaken, this mini is called "Vampire Hunter" and isn't Van Richten. Not directly Ravenloft related, though it would be fine for use in Ravenloft.
Also on the mini front, there's the apocryphal Suul/Azalin miniature, and several Soth minis from the Dragonlance line that could be considered equally Ravenloft-y. (RP Soth standing and mounted 11-064 and Lord Soth's Charge boxed set and the D&D minis Giants of Legend #36 Lord Soth)
And, the "Mouspad" is actually spelled "Mauspad", (It's German). Yes, it's a typo in the Catman Jim's Museum of Rarities .pdf.
Any proof of that Ravenloft Sweatshirt? we discussed a Ravenloft sweater in that same thread, but no one was sure if one was made.
