In my search to find the manufacturer of my Quarter plate camera I've come across some equally anomalous prices, and had a couple pointed out to me.

This one takes the biscuit 25,000/$39,500 They aren't that rare, uncommon yes, but nothing outstanding and not that desirable.

Similarly there was a camera identical to mine on sale in Israel for $2,500, maybe not so bad still a high price but then prices are higher in some markets/countries. Typically a good plate camera will fetch 3 times as much in Istanbul compared to the UK.
