the barbell collars until all production ended. The BUR Numbering System Another factor that distinguished BUR Barbell plates from those of other manufacturers was the use of a unique numbering system. From the late 1930s until the early 1960s, every BUR weight plate had a separate number - besides poundage - stamped into it. These numbers were meant to work with an exercise record keeping system designed by Dave Hall. Even some of the plates that BUR manufactured for other barbell companies had these numbers stamped into them. The BUR numbering system was discontinued in the 1960s. Corporate publications and advertising Publications From August 1939, until January 1940, the BUR Barbell Company published, “The Barbell.” This was a four-page newsletter written and edited by Dave Hall and Mark Berry (who was listed as “Head Physical Trainer for the BUR Barbell Company" at the time). All other publications from the BUR Barbell Company came in the form of advertisements, articles in magazines produced by others, and letters to prospective customers. Advertising Starting around 1941, with time off for the War, and resuming in early 1946, Bur Barbell began advertising in Popular Science magazine and Popular Mechanics magazine. This practice continued until 1964. The End of the BUR Barbell Company In 1966, Dave Hall, died at the age of 58. At the time, there was some industry speculation that the BUR Barbell Company would continue to operate under the management of other family members. However, there is no evidence that this ever came to pass. The BUR Lyndhurst facility was shuttered between 1966 and 1967. The 3-acre property went unoccupied for several years until, in the 1970s, it was sold to a non-manufacturing concern. At that time, the barbell factory was torn down.
