Eric Platford - Chief Quality Engineer} COPY [rubber stamp] R9/IB5515. May 5th. 1915. Re Instruction Book and lubrication of Universal Joint. I agree it would be well to say every 2,000 miles [strikethrough] or once a month. I think cars would do quite well for lubrication, if it were [underlined: thoroughly well attended to] ONCE A MONTH.
