One pair of brass Antique 1900s Classical French Curtain Tiebacks or curtain pole mounts made in France

One pair of brass Antique 1920s French Classical Curtain Tiebacks or curtain pole mounts.
Some patina.
Finish still good.
It stands out from the wall for 18 cm or 7 inches.
These pair work by sliding on to a spike which is driven in the wall.
The wall should be mounted on stone or cinderblock. Plasterboard will not that well. I have shown a photo where the spike is on the sleeve.
It has a holes in the spikes specially for a screw to mount a curtain pole.
Quality pair.
