| To EJJ. 6103 Lr {Mr Ellor} /Wst.3/AP.13.4.37 BATTERY CHARGING RIG The existing open type resistances now being used on the above are over-rated and the wire is continually sagging causing danger by fire due to the excessive heat generated. We want to replace them with up-to-date slider pattern and should be glad if you will order for us:- 1 - 73 ohms. - 3.3 ampere. 1 - 8.5 " -10.0 " 1 - 1.0 " - 8.5 " Zenith single tube type B. resistances.
