Christie's recently sold a vampire hunting kit. Nothing unusual there, but the "probably late 19th century" description is a nice bit of plausible denial. Note, if you will, that the kit once again has stakes and implements made from re-profiled furniture legs. That's something that's only started to show up in the last few years. I suspect a single artist or group is producing all of these and using a cooperative dealer to front them to auction houses.
When anyone claims that a vampire kit is an actual antique, rather than an entertaining example of contemporary assemblage art, they're being dishonest. If they push the point simply ask for documentation of a single period example.
