Cenedese Large Horse Attributed to Ermanno Nason

This is a very large (14in) length Cenedese clear glass Horse that has been attributed to Ermanno Nason from the Gino Cenedese collection. The two front hooves are in yellow or gold colour but not gold leaf etc.
Very heavy weighing 4.2 kg. Signed Cenedese in diamond point on base and has the blue/silver label. Excellent in execution with the right hoof pushing away the ground sideways/the horse sniffing.
If anyone has 100% proof that it is an Ermanno Nason horse, would appreciate hearing from you.
