It is an early GS, but definitely not NOS. The cage attachment bolt is not a Campagnolo item, and the clamp bolts are mangled. I recently bought one in better condition for about a third of the asking price here.

Hi,
I thought this might interest someone here. It looks like an early 5Os Gran Sport
derailleur - but I'm not an expert on these things.
