We are sending into the Stores the sample Ferranti ammeter prepared suitable for fitting to the new instrument patch on the 40/50 HP. chassis. This instrument has developed a short circuit between its terminals and the case and as it is still sealed we would like you to return it to the Ferranti Co., for examination and report.
