Would you also kindly order up for other purposes two of their similar type Z2 resistances of 500 ohms - price each 4/3. Also one of their Z5 type of 5000 ohms - price 6/-; these being convenient resistance units for increasing the range of measuring instruments. When ordering these would you kindly asked the Zenith Manufacturing Company not to supply resistances in which the embedded conductors are not properly covered with the vitreous enamel, as was the case with two obtained [strikethrough] ordered [handwritten] by me for private purposes.
