The one one on eBay is easy to recognize as a repro. Have a look at the white line going almost horizontal on the rear leg - this line should follow the leg curve and go up and then turn left a little bit into the belly of the Pegasus.
Have a look at this one and you can see the difference. But beware, because they are also reproduced in the correct way.
