Beautiful vintage Bouchard bird brooch numbered

Vintage and preowned. Numbered on the back but, sorry, I can’t make out the numbers. The beautiful bird measures approximately 2 1/2 inches from beak to the back of the feathers. It is a proximately 2 inches at its widest point – the back of the feathers. Beautiful blue and green enamel on goldtone metal. There is a scratch on the gold part of the wing and a bit of color loss on the plumes. I think I pictured this clearly.
