- Portable AC Voltmeter Single Range 125 V. But see the different versions - with different scales and other differences - all with the model type 155! Last patents are from 1898. We need advertisements and other documents to be able to tell the starting date which could have been as early as 1898 but was probably a year or a few years later. The different versions show a long manufacture time of decades.
