Is this ebay item (#7212723729), entitled "Campagnolo Nuovo Record Long Cage Rear Derailleur", a real Campy product?

When I googled "nuovo record long cage", I found this posting:
http://www.cyclingforums.com/
"Campagnolo Nuovo Record long-cage rear derailleur. Designed for triple cranksets and/or big freewheels. Perfect for retrofitting vintage road bikes with lower gears. Climb hills easier than when you were racing in the juniors.
This derailleur appears to be almost identical to the Campagnolo Rally long-cage derailleur from the late 70's. However, this derailleur has the "Nuovo Record" parallelogram cage plates. This particular model does not show up in any catalogues that I have access to. It shows no signs of modifications or alterations. It is in excellent cosmetic condition with some normal chain rub on the inside of the cage plates. My guess is that this was produced by Campagnolo in small numbers for sponsored riders. It would be used for difficult mountain race stages where Campagnolo did not want their top riders to be seen using a touring derailleur. This derailleur would allow the use of a wide-range freewheel and/or the 36/42/52 tooth triple crankset that Campy produced in the 70's."
The above post notwithstanding, to me the one currently on ebay just looks like a standard NR whose cage has been replaced with one from a Rally.
Which, BTW, might be an interesting idea. Anyone tried it?
