New to the forum! I have a beautiful Premier vacuum that I am trying to date.. what I have so far is that it has the same roller configuration as the Duplex, mine is only marked Premier without the molded "Premier Duplex" on the front, and the immaculate bag is marked De Luxe. If I am correct, vacs were straight suction prior to 1920, unsure about the next 6 years (I read on your forum that the Duplex came about in 1926, waiting on a Hoover patent to run out on the roller/motor).. wondering if this model that I have ran consecutively with the Duplex as the alternative budget vacuum? Model number begins with 37 and this vacuum is insanely immaculate and the motor is strong. I have not touched it since I found it. Any info would be greatly appreciated!
