Page 711 of the Spring 1929 Sears Roebuck catalog lists a new tube - 4619_WLS which is equivalent to the UX281 rectifier tube. The "WLS" (Worlds Largest Store) brand was either hot branded ionto the base or a paper label on the glass. The Fall 1929 catalog has an entirely new catalog number series and the 4619_WLS became the 57T281
