NEWCASTLE-ON-TYNE 2A, ELDON PLACE, BARRAS BRIDGE. 26th June, 1939 YOUR REF. OUR REF. WES/PW. Messrs. Rolls-Royce Ltd., Car Experimental Department, Derby. For the attention of J.L. Edwards Esq. Dear Sirs, The writer would refer to your request for a fan belt to your section EB.4202 but having an inside circumference of from 47 - 50". We regret to say that our V.165 belt is the longest to this section for which we have mould facilities, and if you must retain this belt section we should like confirmation that it is worth while putting in hand a new mould. We have a number of standard fan belts whose length is between the measurements you specified but these are all to a different section and in each case have a belt angle of 32°. We imagine this would entail the manufacture of new pulleys. The following sizes are between the lengths given by you:- Top Bottom Width Width Thickness Angle Nominal Outside Circumference Inside Circumference V.106 11/16" .401" 1/2" 32° 50.57/64" 47.3/4" V.178 7/8" .517" 5/8" 32° 51.5/16" 47.39" V.129 3/4" .463" 1/2" 32° 51.41/64" 48.1/2" V.134 1" .642" 5/8" 32° 51.43/64" 47.3/4" V.109 5/8" .374" 7/16" 32° 51.3/4" 49" V.102 1" .642" 5/8" 32° 52.27/64" 48.1/2" V.167 11/16" .401" 1/2" 32° 53.9/64" 50" Yours faithfully, FERODO LIMITED.
