| X.1069. Extract from letter of C.A.Vandervell & Co. Ltd., Acton, London, W.3. 1st. March 1921. ref. AG/LRP. X.1069. X.3623 Dear Sirs, We have pleasure in bringing to your notice two new "C.A.V." specialities, and which we do not hesitate to say should command your serious interest, as they are real and ready sellers. X.1069. The "C A.V." ELECTRIC HORN. This is a Horn of the buzzer type, possessing a deep clear note with a dignified tone of exceptional carrying power. The price we think you will agree is extremely reasonable, and so far as quality and finish are concerned, leave nothing to be desired. The enclosed leaflet will give you some idea of this C.A.V. production, but does not do it justice. You must examine one to appreciate its value. If you are prepared to exhibit this new C.A.V. horn in your showrooms and have it properly mounted and connected up to a battery to enable you to give a practical demonstration when required, we shall be glad to supply one at the special discount of 50% off the list figure. Only one of these horns can be supplied at this rate, and if the demonstration horn is sold at any time to meet an urgent demand, it must be replaced at once upon usual terms. | ||
