| Mr Barrington for T.C. for belts RE WHITTLE FAN BELTS This is to confirm conversation I had with Mr Nadin re above to the effect that same should be adopted as standard. Taken allround these are more satisfactory than the Wata-Wata belts. On our Demonstration car one of these Whittle belts has been running for over 3000, whereas the Wata-Wata have to be replaced after about 1,000 miles. E P. X493 | ||
