| To EJJ. c. to RC{R. Childs}/CAP. CAP. ? 6103 Rm{William Robotham - Chief Engineer}/RC.{R. Childs}11/JH.6.1.37. Weston Voltmeter Model 267 No.55301. We have a small instrument of the above type which has been used for a speed indicator, and which for that reason is fitted with a scale calibrated in revolutions per minute. The control spring of this unit is broken and the zero adjuster defective. We would like the makers to overhaul and repair it and at the same time make it right for use as a voltmeter with a 25 volt range. Rm{William Robotham - Chief Engineer}/RC.{R. Childs} | ||
