| -2- Ha/Wst.4/MA.15.4.35. Cont'd.{John DeLooze - Company Secretary} Conclusions. In our opinion sample No.3 is the best with Sample No.1 second and Sample No.2 third. Although No.2 is inferior to either 1 or 3 we consider that if the cotton braiding was waxed more effectively it would be quite suitable for use on voltages up to 200. Ha/Wst. | ||
