DescriptionBrass; garland with straight upper edge and floral decoration in repoussé (roses, scrolling foliage, empty cartouche flanked by trumpet and banner); Saxon rim with iron wire insert; three-part flower-decorated ball with groove; rolled ferrules with fluting design of two slightly different styles (some by Rodenbostel, some replaced by Woodham); slide at back bow with clock-spring return-mechanism and fine-tuning device, slide lowers the pitch by a semitone (D) or slightly more (F), but is not long enough for whole-tone alterations.

This is the earliest surviving English mechanical slide trumpet known to date. The instrument was originally made as a natural trumpet by George Henry Rodenbostel and then converted into a slide trumpet by Richard Woodham. The conversion to a slide trumpet may have taken place in collaboration with the trumpeter John Hyde, who claims in his "Preceptor for the Trumpet" (London 1799) to have been the inventor and Richard Woodham the maker of the new slide trumpet. The period of activity of George Henry Rodenbostel and Richard Woodham overlapped, they were both active between ca. 1770 and 1789; slightly different ferrule styles between original and altered parts may indicate, however, that they did not collaborate in the conversion process.
