I have a small device call and "The Up and Down" model LB2 -voltage booster manufactured by Service Instruments Co. of Chigago. It switches the voltage up or down by 10 volts. The input is 100 to 130 volts the output is either 110 or 120 volts at 3 amp's.  It is, of course, a service device what exactly is was used for I don't know.
