| -2- Unfortunately, there is one difficulty in connection with this Switchboard, and that is it will not be suitable for an earth return system, and if it is desired to be used as such, it will be necessary for us to construct a special Switchboard throughout. The question of prices for the above components is receiving our consideration, and we will let you have details in the course of a day or so. Assuring you of our best attention at all times, Yours faithfully, Per Pro C.A. VANDERVELL & COMPANY, LTD., (sgd) E.L. ENGINEERING DEPARTMENT.
