| ROY. {Sir Henry Royce} from EFC. {E. Fowler Clarke - Electrical Engineer} SPARTON S.O.S. Deluxe Horn. Some time ago we had one of these for test, the makers being Messrs. Alfred Graham & Co., St.Andrews Works, Crofton Park, London S.E.4. Now that we are again considering a departure from the Klaxon motor horn to one of less raucous type, we should be pleased to be favoured with a further sample of the above for 12-volts and would prefer the senior type.
