Phantom Slipper Drives - Chassis No.60-EF - Martin. In accordance with the request from 'C' on the 13th ult. we sent to 'N' the necessary material for dealing with the slipper drive of the above chassis, in a similar manner to that recommended by the Experimental Dept. and which was applied so satisfactorily to Major Walker's chassis 6-LF. I now have a report from Br.{T. E. Bellringer - Repair Manager} saying that the job has turned out very satisfactorily, and is quite a success, the "galloping knocks" are entirely cured.
