Dear Sirs, Re - Boyce Electric Clock No. 696. With further reference to the above clock the faulty operation of which was originally described to you in our EFC1/AD. of November 12th, we have now further to report. You will remember that this clock was returned to you and that although you could find nothing wrong with it you opened it up for investigation before returning it to us. We acknowledged the second receipt of this clock in ours EFC3/AD. of December 10th telling you that we would advise you of the results of further tests which we should be making, these results are as follows :- The clock ran satisfactorily on the bench for six days after which it stopped again in precisely similar circumstances to those previously reported to you and again there was no circuit through the clock on the voltmeter test. On this being reported to the undersigned he suggested that we should endeavour to re-start the clock by shaking it as it may have been shaken in transit to the English Clock & Watch Manufacturers; by so doing the clock was re-started. | ||
