The first record issues on the Regal Record label in February 1914 were re-issues of existing records from the Columbia Record Catalogue: G-6105 to G-6559, G-6440, G 6441 (English Catalogue) and G 6560 to G 6639 (Scottish Catalogue). Catalogue numbers starting from G 6000 were used at later dates.[1]
In November 1921, 12 inch records were introduced, commencing at catalogue number G-1000.[1]
From around 1923 onwards many earlier recordings were re-recorded acoustically and released under the same catalogue number as the originals. For catalogue numbers below G-7963 (released July 1923) these may usually be identified by a matrix commencing with an 'A', rather than being completely numeric.[1]
The Western Electric electrical process of recording was introduced in February 1926. Those records re-recorded using this process invariably have their catalogue number suffixed by 'R'.[1]
From March 1930, all new releases were prefixed in the catalogue by 'MR', commencing at MR1.[1]
