Undocumented American Vampire Killing Kit
This kit was apparently sold by the Stevens Auction Company, and it was reportedly made in New Orleans in the 19th century. Apparently Blomberg really got around.
Potentially relevant is this text, from a website describing an identical kit finished in green velvet:
This box is entirely real. I saw it in 1992 on exhibit at the Mercer Museum in Doylestown, Pennsylvania, USA. The printed text is in English and is exactly as reprinted above, including the punctuation - I was so struck with the box I copied the words down on a spare scrap of paper. The curators there date it to between 1825 and 1850, mostly on the basis of the pistol.
Once again, we see the familiar attached interior label:
Vampire Killing Kit
The accoutrements for the destruction of the Vampire
This box contains the items considered necessary for the protection of persons who travel into certain little known countries in Easter Europe where the populace are plagued with a peculiar manifestation of evil, known as Vampires...
