[78-L] Decca 23000 series

[Harold Aherne]

Does anyone know when Deccca's 23000 "Personality" series was inaugurated? The first
issue (by Grace Moore) was recorded in March 1936 but I'm not certain when it was actually
made available.
 
If the 23000 block was indeed inaugurated in 1936, did it ever use the sunburst design? On
early Personality discs I've only ever seen the block-letter style (on a wine-coloured background
as in the 18000s, with "Personality Series" under the label name). By 23277 (recorded in 
September 1943) the familiar serif-style Decca logo was in use, but there had been another
briefly-used variation--the script Decca label with "Personality Series" in small letters above
the label name. Was the serif-style used before the fall of '43?
