А как же моно матрицы P?  Кто их нарезал?

Информация про МОНО...
The engineers had their “own” LP’s to take care of. It was usually the same cutting engineer who did a new cut if a new Master Lacquer was needed.
Decca had also dedicated Mono cutters who only took care of Mono records.
Guy Fletcher has done almost all Rolling Stones mono LP’s.

А ещё Stan Goodall их моны нарезал, хотя и специализировался, в основном, по классической музыке.

Моно версия этого альбома имела два варианта. Первый нарезал, тот самый неизвестный Р, а второй и стерео – К ( Tony Hawkins)

The mono LP of Satanic is existing in two different versions. The original master tape was mixed two times, the first one was used for mono records only and the second one was used both for mono and stereo records. The two mixes used for pressing mono records can be identified by the matrix number

The first mix that was used on mono records has the following matrix number:
ARL-8126-1P on side one and ARL-8127-P1 on side two
The second mix that was used on later mono records and on all stereo records has:
Mono: ARL-8126-T2-2K for side one and ARL-8127-T2-2K for side two
Stereo: ZAL-8126-T2-5K for side one and ZAL-8127-T2-5K for side two

The last two digits may change from one record to another, the letter is identifying the person who cut the original Master Laquer, also called acetate. The last number before the letter indicates how many times Mr K has recut a new Master Laquer. The key indicator on Satanic is the T2. Decca used to identify a new mix by adding the code T2 and Satanic is the only LP that has been cut and pressed from two different mixes and where it is possible to confirm this through the matrix numbers. This way of working was common on 7” single records, they had T1 indicated that it was Take 1 of the title. If the producer rejected the take he would remix the track and then it become Take 2.

A LP that do not have the T2 in the full matrix numbers is a true mono mix. If the LP has the T2 code, then it is basically a stereo mix that has been folded down to one channel for mono sound. You can actually hear the difference in between a “non T2” true mono pressing and a T2 stereo fold down to mono pressing. Take the song “The Lantern” for example, there is a bell tolling in the beginning of the song:
A true mono record has the bell tolling three times before the music starts (matrix ARL-8127-??)
A fold down from stereo to mono AND a real stereo LP has the bell tolling two times before the music starts. (matrix ARL or ZAL-8127-T2-xx)
There may also be other differences on the sound.
