Re: American Standardisation Sheets 29-39. --------------------------------------- The above Standardisation Sheets were received here on the 10th inst. 1923 You may remember that it was arranged on February 23rd that the date on which an alteration was to be brought into force was to be inserted on the standardisation sheet and was to be sufficiently far ahead to allow Mr. Royce properly to examine the proposed changes before he authorised their introduction. We give below a statement showing the proposed changes embraced by the above sheets and the dates on which they are to come into force. Will you please let me know if there is any reason why the official understanding has not been adhered to in connection with these sheets. No. 29. Change Gear Box.
