Brass Lion Door Knocker - retailer New Old Stock - French Vintage

I found this brass door knocker in the form of the head of a lion recently at a brocante, it has never been used, and comes with the original screws and retailer fittings. It is however over 20 years old as the (very battered box) was priced in French Francs which have not been legal tender in France for 20 years.
The condition is very good, it has some minor areas of discoloration but nothing that wouldn't be expected after 20+ years.

Height (Lion's Head): 12cm x 9cm or 4 3/4" x 3 1/2".
Overall Height (including knocker): 16.5cm or 6 1/2".
Weight: 670g.
