is now available from Lodestone Automob:les Ltd., 8 Winton Court, 15 Lovelace Road, Surbiton, Surrey, the recently appointed U.K. concessionaires. Three models are suitable for use on commercial vehicles, two of these being available in a variety of forms.
The Aquila is a twin-trumpet pneumatic instrument which can only be fitted to a vehicle already having a supply of compressed air. It has a two-tone note and costs £6 2s. 6d.
Most recently introduced are the Capriolo twin-trumpet (harmony only) electro-pneumatic horns. On these the trumpet diaphragms are activated by compressed air supplied from an electric-motor-driven compressor. Plastics or chromiumplated brass trumpets are available and these cost £6 17s. bd. and £7 12s. 6d. respectively. Although producing the same volume of sound as normal twin-unit all-electric horns, it is said that they can be heard about twice as far away.
The most diverse range is the Daino. Units with from one to four trumpets are Made and these can be had to play in harmony or in spaced sound or in both playing patterns, the change being effected by a dashboard-mounted control knob. The Daino horns are slightly more powerful than the Capriolo types and more expensive. The single-note, single-trumpet costs £8 and prices go up to £23 for the four-trumpet instrument. The Daino horns operate on the same principle as the Capriolo and both types are available for 6-, 12and 24-V. supplies. In all cases postage and packing adds 5s. to the price.
