The 500 telephone is an enduring classic of American design. It was first available in 1949 or so and was made for the better part of 50 years. Henry Dreyfuss designed the first 500 for Bell Labs (read about the design process in this book) as a model to improve upon the WE302. Some of the design shortcomings of the WE302 were fixed -- such as the creation of a dial with the numbers and letters outside of the path of one's finger, which tended to wear out the metal plate's porcelain coating, and making the numbers molded through and through the plastic so that they could not be worn off either. Early 500 sets used a #7 dial and later ones a #9 dial. This model became so successful that other companies made them under license from Western Electric (Stromberg Carlson, Kellogg - later ITT, Comdial, and Northern Electric).

NOTE: In case you are not already sure, please verify that your telephone service will accept pulse dialing before you order. Many of the VOIP (voice over internet protocol; digital telephone) systems no longer accept pulse dialing. FiOS and standard "POTS" copper wire systems almost always accept pulse dialing, but it's good to check. Our pulse to tone (click here) converter should allow the rotary dial set to work on many VOIP systems.
