Date: 21-9-1928 Order No. TC129 Customer's No. X. 3478 Re test of Viscometer Instrument This instrument has passed our specified tests satisfactorily & reads 1% high on each side of the scale. There is a very slight sign of stiction of the needle at one point on the discharge side of the scale, but this can be considered passable. This instrument has not such a nice even black finish as our Std but the dial is very nicely graduated. This instrument should now be put on an experimental car for test over a period of time if it is likely to be standardised. Signed: E.J. This Sheet must be filed on completion of the work. | ||
