| 1135 To Les.{Ivan A. Leslie} Rm{William Robotham - Chief Engineer}/Ed.{J. L. Edwards}3/JH.22.8.39. Ferogrip Fan Belts for 25 HP. chassis. E.56204. We have tried the V.155 fan belts on three chassis in the repair department, and find that they are too short. We recommend that you communicate with Ferodo's with a view to obtaining a belt of internal circumference 40" - 40.5" which will probably be satisfactory. Rm{William Robotham - Chief Engineer}/Ed.{J.
