If he's got THAT in a box in his living room, he would kind of have to.
As is the case with most antiques, the older a collectible medical relic is, and the nicer it is, the more you can plan to shell out for it. A 19th century wax teaching model isn't equivalent to, say, a 18th century surgeon's kit with ivory-handled bone saws in a velvet-lined hardwood box. But it ain't chump change, neither. If Bash got this out of the estate for less than a few thousand, he should have done it wearing a balaclava and gloves.
Anatomical waxes (wax moulage) are most likely to be found in older, less squeamish medical museums these days, but private collections do exist; Christie's auctioned one off piece by piece in 2001 (NWS). Bash's pride and joy is modest compared to some of the waxes featured in that lot, but he's a doctor, not an oil baron.
His original object of interest, leech jars, are... well, pretty much exactly what they sound like. They were jars for holding leeches, which surgeons used (and still use) for bloodletting. They can be anything from glass bowls to gilded ceramic urns. And they're popular with buyers, since they're not aesthetically revolting/mysterious, plentiful, and wonderful conversation pieces. They're also a bit of a minefield for the serious collector of medical antiques, as fakes and replicas of the things are as common as muck. (Translation: Never buy one on eBay.)
And "Syphiology" was a real field, before the advent of simple antibiotics. Syphilis was capable of some truly heinous disfigurement when left unchecked; Syphiology and dermatology were basically interchangeable specialties prior to penicillin. "Syphiology" also has one of the lowest numbers of search results for a correctly-spelled single word I've ever seen, for those of you into Googlewhacking.
I could get really, really obnoxious about Bash's hobby... One I would probably have if I ever hit the lottery, to be honest. But Googling "medical antiques" or just visiting one of my favorite sites on the subject is enough to satisfy, I think.
More later!
