Weston routinely used a single model number for meters with different scales leading to the conclusion that the model number was likely referring to the meter movement rather than the covered range(s).
The Weston model 455 was available as a single-range voltmeter that will measure AC or DC voltage up to 125 volts (as shown above). The scale is specially marked in red at 115 volts. The meter was high accuracy and lab calibrated. A fitted case was optional.
The Weston model 455 was also available as a three range AC voltmeter measuring 150, 300, and 750 VAC (as also shown above). It was also high accuracy and lab calibrated.
