Singing bird box
"Bontems can be regarded as the father of the modern singing bird box, after its simplification of the movement and improvements in the sound. A successful house lauded for the realistic quality of their songs, they exhibited in several Universal expositions and fairs where they were awarded with 43 medals of gold, silver, vermeil and bronze in Europe, the United States, Asia and Australia. They were suppliers "to her Royal Highness the Queen of England", among others."
