1851 Great Exhibition: Official Catalogue: Class X.: John McNeill

512. MCNEILL, JOHN, 140 Capel Street, Dublin — Inventor and Proprietor.

Cambridge cavalry field-trumpet bugle, for executing trumpet and bugle field calls without having recourse to a second instrument.

Bulb cornopean; the bulbs are substituted for angles, and curved passages are thus obtained for the wind without enlarging the valves, or increasing the friction, which gives improved quality of tone and facilitates the execution.
