November, 1936. Messrs.Hallam,Sleigh & Cheston, Widney Works, Bagot Street, Birmingham, 4. For the attention of Mr.J.H.Booth. Dear Sirs, We thank you for your letter of the 25th. inst., and note that you are making up a sample top bonnet hinge using our .104 sheet aluminium for the bonnet plates and the heavy gauge Widney hinge as used by Messrs.Humber on their Pullman Saloon cars. We note that you have no machine for folding this thick bonnet material and agree to your doing these samples by hand, even though a perfect job may not be obtained. As it is over a year ago since we first asked you to supply us with these samples and much of the history of the job has been lost, we agree with your suggestion that your representative should make an appointment to call on us to discuss the situation as soon as convenient with a view to your producing for us a design showing how to fit your bonnet hinge to the top of the Bentley bonnet, and subsequently supplying us with a complete hinge unit so that we could fit up a Bentley car with such a bonnet. At the same time we should like you to consider whether it is possible for you to produce a hinge which would give a greater angular opening than 135º, as whilst such an angular opening is just permissible on the Bentley bonnet it is not so on the Rolls-Royce bonnets, because the side hinge is at the top shoulder of the bonnet causing the side panel to be very long. With 135º of opening the back corner of the side panel fouls the scuttle. Contd: | ||
