Subject: [CR]4-hole cage Campagnolo front derailleur

Cyclo-network is offering a 4-hole cage Campagnolo front derailleur http://ebay.com/<blah>

One of these was offered last year and the word on the CR was that this was offered for a very short time and that chains perhaps caught on the 'extra' hole of the cage. Does anybody know more about this variant? Such as when it was produced, was it sold throughout the world or in a few markets only. Is the front plate of the clamp original (none of the other variants seem to use the same front plate shown in the auction picture?)

What is consensus, should it be worth more because rarer, or less because it didn't perhaps work as well as the three hole version?
