I was given a box of 1930s memorabilia today. A 1930 Wirt voltage regulator ( dimmer switch). It has 7 adjustments as seen through the small window. Will post the rest of the items when i can indentitify them. ALIMG_0390.jpg

Re: AC voltage regulator

I assume mine is just a rheostat, becaue it gets pretty hot and it looks very simple and compact.
