We are at the moment testing two alternative water pumps to the standard Wraith water pump and would like cost figures for each of these pumps as well as for the standard pump. The first one is to SCD.574 and SCD.234, while the second one is to SCD.584, with pump casing mounting modified in accordance with SCD.574. We attach herewith prints of SCD.234, SCD.574 and SCD. 584. Will you please let us have cost figures for the three pumps - details of the above mentioned two experimental pumps are available from By/Ald.{F. Allwood - Experimental Design} as EXS. details. The Skefco ball bearing unit used on SCD.234 can be taken as costing 7/6d. Rm{William Robotham - Chief Engineer}/Std. | ||
