Antique Vintage Solid Brass Lyre Harp Music Stand Musical Door Knocker

Description

This is an antique or vintage solid brass lyre/harp music stand door knocker.
I would estimate it dates circa 1920s or 1930s, though it could actually be a little earlier.
It measures 7 3/8 inches high (18.7 cm). It measures 4 3/8 inches wide at the top and 4 1/8 inches wide at the bottom (11.1 cm, 10.5 cm).
There are a number of reproductions of these available, but this one is definitely early. It’s a very high quality piece.
There are some numbers stamped in the top left corner. Possibly 91?
The door knocker has tarnished and worn beautifully.
I don’t see anything wrong with it.
It weighs a touch over 1 lb. 13 oz. (830 g).
