One pair of brass Antique 1920s large Classical French curtain pole mounts made in France

One pair of large brass Antique 1900s French Classical curtain pole mounts.
It stands out from the wall for 18 cm or 7 inches.
These pair work by sliding on to a spike which is driven into the wall.
The wall should be brick, stone or cinderblock. Plasterboard will not work that well.
Quality pair.
These would be used to mount a curtain rod on with two screw in nails to mount poles.
