| X2764 Hs.{Lord Ernest Hives - Chair} BY/C9/H.{Arthur M. Hanbury - Head Complaints} 23. 5. 23. 40/50. HP. CHASSIS 9-YG. STANLEY TUBBS ESQ. We attach copy of BY13/P. 26.4.23. in connection with broken valve springs and burnt Exhaust Valve which occurred on the above chassis, and no doubt you will remember that the question of the Exhaust Valve burning out was discussed with you, when it was agreed to have the two cylinder blocks returned for the purpose of investigating the reason for same. The customer now agrees to this proposal, therefore new cylinder blocks are being instructed and will be fitted by Cricklewood, and the originals returned to these Works when they will be handed over to you, when we should be glad if you would take an early opportunity of going fully into the matter and let us have your report.
