The Antique Trader article about the estate sale has this to say about the kit:
The vampire killing kit was made around the early 1900s, Stevens estimates. It contains four stakes, crosses, mirrors, guns with silver bullets, potions, vials, herbs, medicines, holy water and garlic. In October, Stevens Auction sold another, earlier vampire kit (circa 1800) for $14,850.
This part reads like it was lifted right out of a horror film:
But by the time Wadginski arrived in the mid-1960s, that business had already shut down and there was little left, save for the buildings and history of the town. Hollow Rock was named, legend has it, after a meteor that crashed there hundreds of years ago. The space rock, which was in fact hollow, today still has inscriptions that were carved by the Native Americans who live in the region at the time.
The second someone told me the town was named after a hollow meteorite covered with strange native inscriptions, and that the rock was still around, I would have politely told my real estate agent to cross that location off the list. Years of watching B-movies has taught me it's just a matter of time till whatever was inside starts wreaking havoc.
