Lyntone was also cutting master lacquer, plating (i.e. metal works) and pressing vinyl of all sizes and very occasionally they self-released records with Lyntone as the stand alone label.
Founded 1961 as Audio Plastics Ltd. by Paul S. Lynton after he left the Rank Organisation's company "Rank Audio Plastics". Early Audio Plastics Ltd. releases also carry a LYN number. Originally based in London's Regent Street, the plant later moved to Holloway, North London. The rise of digital formats and the demise of the novelty factor amongst others, led to selling the plant to Damont Audio Ltd. in 1986 and the final closure of the plant came in June 1991.
Lyntone pressings can usually be identified by a pattern, consisting of LYN or L, followed by 3 to 5 digits, e.g. LYN-943, LYN 2211, LYN.11095. Sometimes only the numbers are present.
Add LYN or L and the numbers as they appear (e.g. LYN-1234 or LYN 1234 or L 1234) in the runouts as company cat# for Pressed By but without the tailing numbers/characters (e.g. IL, 2U, IT, etc.). When there are two different LYN numbers (i.e. one per side), add Pressed By twice and add the respective LYN number (see here for an example).
The tailing number (I, 2, 3) and letter identify the studio that provided the (number of) Mothers (e.g. IC, 2M):
C = CBS Studios, London,
CR = County Recording Service,
E = EMI's Abbey Road Studios (unless specifically stated Penthouse)
M = Master Room,
S = Unknown, likely Strawberry
T = Trident Studios,
U = Unknown, likely IBC/ Portland Studios
W = The Music Centre, Wembley,
X = The Exchange,
Y = Pye Studios (until September 1980)
Late 1980, this was extended / replaced by additional letters (after a leading number):
CBS: Mastered At CBS Studios, London
CRS: Mastered At County Recording Service
CTS: Mastered At CTS Studios
EMI: Mastered at EMI's Abbey Road Studios
EX: Mastered At The Exchange
MSR: Mastered at the Master Room
PRT: Mastered At PRT Studios
SC: Mastered At The Sound Clinic
SM: Mastered At Strawberry Mastering
TD: Mastered At Trident Studios
TH: Mastered At The Town House
TO: Mastered At Tape One
TR: Mastered at Trident Studios
UT: Mastered At Utopia Studios
In those case, the studio can be added with Mastered At.
Note that the leading I (e.g. ITO) is in fact a 1 (see 2TO or 3TH).
