The Sterno label was used by the British Homophone Company, launched in 1926, and recorded by the Gramophone Company at its studios in Middlesex, UK. Rust [R] ranks their quality ‘as good as anything to be found on HMV and Zonophone' ; but the early quality declined over the years. 

Neither Rust [R] nor Field [F] show these two Sterno labels, although they show two other designs, one of which is blue, apparently the first Sterno label, which was discontinued in 1928. This was superseeded by the rich red label, printed in gold - classy but hard to read. The differences between the two labels sshown, and those of Rust and Field is, on L035, the words ‘Electrical Recording', and on L025, the strobe-like design around the perimeter of the label. Was this used in any way to ensure the right turntable speed?    

The catalog numbers started at 100 and reached over 1,500 issues, the last in June 1935 when EMI and Decca bought a participating share in the entire record catalog of British Homophone (the Homochord label, qv). Popular artists included the pianist and band leader Charlie Kunz, the orchestra leader Mantovani, the comedians Flanagan and Allen, and ‘some famopus British bands'. 
Sterno is also known for reissueing a number of masters from the Gennett catalog in 1920 and 1921, and ffrom Vocalion in 1923, as they were inherited along with the Homochord catalog.  They were apparently Hawaiian guitar records, my second most loathed music after country and western!
