Odd voltages, as what TEXAS RANGER mentioned 150 Volts. ( they do, did exist )
I have a Moser Baer Masterclock which has primary tappings 110, 125, 145, and 220 Volts.
See if I can make a picture of it
Something at around 145 / 150 V ac must have existed in some parts of Europe otherwise manufacturers wouldn't provide that option.
In older cities in the Netherlands 127 / 220 Volts was used. It is now almost obsolete and mostly 220 Volts is taken between phases.
