Sonora Swing

Series established by Sonora (2) in 1936 for jazz releases. Between 1936-1940 the releases had the same black and red label as normal releases from Sonora (2) but with the text "Swing Serie" and a special number in a square on the label. These special numbers range between 1 and 60. Please add these releases with Sonora (2) as label and Sonora Swing as series. After 1940 (to 1948) a special black and yellow label were made and the records were given a special number series with numbers between 500-673. Some of these releases had also a special number in a square on the label. Please add all these black/yellow releases with Sonora Swing as label. In the case there are a special number in a square, add this as a series number with Sonora Swing as series.
