The convoluted or folded ear trumpets were sometimes called bugle ear trumpets because of similarities in shape to the musical instrument.

They were also referred to as Bonnafont trumpets after Jean Bonnafont a French army doctor and otologist who was said to have invented this design around 1850. Similar English forms may pre-date this, perhaps not surprisingly as the bugle has been around since the last half of the 18th century. This fine small tin example made to a high standard has survived remarkably well. The black japan lacquer finish can be seen on the inside of the trumpet. The outside has lost much of the original finish but the gilt border can still be seen and pretty as it is now in its day it would have been a stunning example. The ear piece is made from soldered tin.
