Confirming our verbal conversation, will you please arrange to obtain the latest pattern of ammeters from the Production Stores, for the various experimental cars, so that the modifications proposed, may be on test. The modifications consist of the addition of a lock washer in the screw on the terminal posts, and a bush and washer where the terminal post passes through the back plate. Instruments with these modifications will be identified by the presence of red paint on the back. BY/RB{R. Bowen} | ||
