With glass, that book is 'Eighteenth Century English Drinking Glasses, by L.M. Bickerton, and for English, base-metal candlesticks, the above tome - written by Eloy Koldeweij - seems to be the one, as I have just discovered. The Bickerton book can be picked up for about £50, and the Koldeweij one for between £90 and £150, plus delivery. Delivery is not cheap - it weighs about 10 pounds, and seems to have about 600 photographic illustrations - I will not know for sure until I have acquired my copy.
There is a massive conflict of interest here, which teeters on the brink of paradox. In order to obtain your object of choice - if 'choice' it is - at a price which suits your budget (we are talking bargains here) one has to rely on the fact that the seller or auctioneer does not know the value of the item they are selling, even if they have a clue as to it's age or provenance. But then the value of said item is entirely dependent on it's desirability, and the more people that seek out these objects, the more desirable they become. If you need to finance your obsession by selling on the odd item at a a good price, the potential buyer needs to know the maximum value of it before he is willing to part with the cash. Sooner or later, your average car-boot salesman will own a copy of Bickerton or Koldweij, in much the same way as your average burglar used to own a copy of Miller's Antiques Guide before the internet made it obsolete.
I was trawling through a Christie's auction catalogue the other day and came across a late 17th century brass candlestick which looked - to my eye - pretty similar to others that I had seen for about £200, and not visually as nice as the one I bought recently at auction for £40. The Christie's one sold for £10,000. That was when I started to look for the definitive book on the subject because, unlike the world of glass, I do not personally know any experts on base-metal candlesticks.
Of course, I derive great pleasure from the hunt for these type of things, but it is a strange, excruciating pleasure. I have never been attracted to sado-masochism, but I suspect that the pleasure derived from it is similar to mine when competing for glass, or - more recently - candlesticks.
I read a few years ago that - following clinical tests - every sado-masochist tested by the research scientists who made the report, had one thing in common: mild, frontal-lobe brain damage. The brain-damage is not the sort which is noticeable from the outside, as they all lead perfectly ordinary lives when not down the club, trussed up in leather and being beaten by dominatrice, and - if questioned - those on the receiving end of the lash would have said they were leading perfectly ordinary lives on their nights off too.
Perhaps all those years of drug and alcohol abuse are starting to pay off?
