| -2- demonstrated actually on the car, as the optical design is such that it is essential that the lamp is fitted exactly in accordance with our instructions or the best results will not be obtained. We have had one or two unfortunate experiences of this, owing to the pruchasers not realising the optical properties of this lamp, which we have no doubt you yourselves will realise when we explain the technical and optical design. Trusting that this proposed arrangement will be suitable to you and that we may hear from you on this matter by return. Yours faithfully, for BANTING & TRESILIAN, LIMITED.
