Gunbroker.com Vampire Killing Kit, 2003
This kit was reportedly posted for sale at a firearms site (gunbroker.com), but I have only second-hand references. This is reportedly another kit from Ernst Blomberg, who appears to have been a sort of brand name for souvenier vampire kits sold to tourists in the late 19th century.
Compare to this kit, which professes the same provenance.
