Thanks, friend. I thought it might be worth a lot more. I seem to recall that baout 20 years ago I saw one in a specialist vintage camera shop near the British Museum in London and I was amazed at the time at the price beng asked. I didn't have one then and wasn't particularly interested so I didn't make a firm mental note of the price but it seems it was something like 200 plus. Is my memory playing tricks? I thought rarity value was the reason for the price. PS KNow any two fanatics I can entice into a biddng war?
