The American company Sears Roebuck, with its head office in Chicago sold the standard range of American designed and made radio tubes from 1925. A few small manufacturers made these tubes and they were branded WLS (Worlds Largest Store). The company allotted each tube a four digit type number. The company also sold regular branded tubes such as Radiotron, Cunningham, Solartron and Meteor.
