I’m looking for information on Ingersoll electric razors. I have searched and searched and all I found was one at the Museum of American History - Smithsonian. Does anyone know anything about them? When made or sold? Why they stopped making them? I contacted Ingersoll, only to hear back they only handle watches, but I know they made a limited number of electric razors. I found an ad for them online from the 30’s, but nothing else. Thanks in advance for any information, even if you can just point me in the right direction!
