We have found this ammeter to be so satisfactory that we would like you to obtain for us from Messrs Weston three sample ammeters which conform to the dimension requirements of our standard 20/25 instrument patch. The dial appearance and lettering should be as close as possible to the existing standard ammeter, but in order to get tests of these ammeters very quickly, we would be prepared to accept their standard dials. BY/RD. will be able to furnish particulars of the instrument case suitable for our patch. These instruments are very urgently required as until we have a satisfactory instrument we cannot go into production with any of our new vibrator regulated dynamo schemes on chassis.
