I'm guessing a 100v machine won't mind 120v too much.
They are fine on 120 but out of an abundance of caution I normally use them on 100 volt transformers I have around the house for our assortment of Japan market vacuums. One of my D795s needed a new motor and main board. The originals were overheated charring the main board and melting a connection. Apparently a common enough problem that Lux had a kit with a new main board, motor and wires. The new motor, a powerhouse from Domel, says it is rated for 100-127 volts. 50-60 Hz. The cord has 115v/25A stamped on it so I run that one on regular 120 volt house current. I really love these old Luxes.
 
Congratulations! Is that a Japanese logo on the bag door? Is the power nozzle a model E3? I have a limited knowledge of the AB Electrolux power nozzles, but it seems that the E3 was produced for a long time and had different covers if not other variations. France PurificationLux lists a model E34, too, which was made from 1966 to 1992.

Not sure what that logo is. Normally I remove vac shop stickers but if it is something peculiarly Japanese I will probably leave it for the weirdness factor. My working D795 has a Japanese vacuum shop sticker on it that I will never remove.

The power nozzle is a Ze3. The graphics on the Ze3 and the white hoses are not correct for that model Lux but they are correct for my older D730 and my Viking V720 ( much nicer power nozzle than a noisy old Vibragoomer or the later and painfully loud Eureka Rugmaster / Rugmuncher thing some of the Viking branded ones came with ). That is half the reason I bought it ! I have a spare gray hose of the style the D770 would have come with and an extra dark gray Ze3 with the red Lux logo, also period correct for the D770. This was kind of a two-fer for me because it lets me complete two older Luxes I have.
