"His Master's Voice" label designs

Below are all known UK label designs for "His Master's Voice" catalogue sequences that included classical repertoire between the end of WW2 and the end of 1959. All sequences are mono, unless stated. All sequences concentrated singly on classical music, unless stated.

78s

Label designs for DA and DB sequences are identical, slight variations in rim text and text placement notwithstanding, and label colours are occasionally lighter or darker. The same goes for the B and C sequence issues.
The Plum Series was, presumably, a popular music sequence including popular classics.

Red Label series 10" (DA prefix; 12" DB prefix label is identical)

Plum Label series 10" (B prefix; 12" C prefix label is identical)

LPs

The Plum label series was a popular music sequence including popular classics. With the stereo labels, the first letter of the prefix matches those of the Red and Plum mono sequences.

Red Label series 12" (ALP prefix; 10" BLP prefix label is identical)

Plum Label series 12" (CLP prefix; 10" DLP prefix label is identical)

White & Gold stereo label (ASD 12" series; 10" BSD, 12" CSD & 10" DSD labels are identical)

7" SPs (Short Play)

The SP format, now better known as 'singles', was confusingly originally viewed as a Long Play format (i.e. stacked on an autochanger record player, as per earlier 78 'albums'). The first releases, all from EMI, had a large centre hole as per the original US RCA Victor format, for playing on early 45 rpm players with large spindles.
Again, the Plum label series was a popular music sequence including popular classics.

Red Label series (7R prefix; large spindle hole)

Red Label series (7R prefix; push-out centre)

Plum Label series (7P prefix; large spindle hole)

Plum Label series (7P prefix; push-out centre)

7" EPs

Yet again, the Plum label series was a popular music sequence including popular classics. Here, however, it was joined by the green series, which was similarly a popular music sequence including popular classics.

Red Label series (7ER prefix)

Plum Label series (7EP prefix)

Black Label series (7EB prefix)

Green Label series (7EG prefix)

Red Label series stereo (RES prefix)

Plum Label series stereo (PES prefix)
