The Beatles – Beatles For Sale

Hello friends, just bought a this cd...but can not trace the version of it. its CDP 7 46438 2 [DIDX 1257] MADE IN JAPAN, on the disc..Could somebody help me out with discogs link? Thanks

At the "6 O'clock" position on the inner groove area is the matrix number with a -1 or -2 etc.
For instance, Beatles For Sale in stereo is YEX 142-1 (etc.).
The "1" means the FIRST LACQUER cut from the master. -2 the second etc.
At the "9 O'clock" is a number which tell you what "mother" was used to generate the stamper actually used the press the record. A number of "mothers" are generated from the lacquer. Obviously a "1" means first mother generated from the lacquer. A "5" means it was much later--the fifth mother generated from the lacquer.
At the "3 O'clock" position there will be one to three letters, which are codes associated with numbers as follows, which tell you what stamper was used to press the actual record:
G R A M O P H L T D (gramophone Ltd)

G=1 R=2 A=3 M=4 O=5 P=6 H=7 L=8 T=9 D=0

Therefore, if the letters say "GR" that is stamper 12. "O" is stamper 5 etc.
YEX 142-1, mother 1, stamper G is the very first pressing of "Beatles For Sale" in stereo: first lacquer, first mother, first stamper.

YEX 142-1, mother 4, stamper RLT. That would be first lacquer, 4th mother and 289th stamper generated from that mother.
