Pathé Marconi, Chatou

French shellac and vinyl pressing plant. Operating under this name from 1936 until the end of 1971. From 1972 onwards operating as Pathé Marconi EMI, Chatou. Vinyl matrix scheme: Mx ###### where x is the format identifier: '1' for 7" (33 1/3 RPM) '3' for 7" and 10" '6' for 12" or LP The 6 digit numeral code is a unique plant identifier and can normally be added as LCCN number with Pressed By. However, it should be noted that Pathé Marconi also serviced foreign sister companies from the Electric & Musical Industries Ltd. group who did not (yet) have full manufacturing capacities. When a release explicitly states it was made outside of France, this indicates a local pressing using Chatou plates, in those cases please credit with Mastered At. Usually (but not always) both runouts share the first 5 digits and the last one is incremented. Example: [r11586322] 280700 280701 Only enter the 6 digits, without the Mx, commas, dashes or blanks. Various other strings can be found beside this matrix scheme, referring to the label's cat# or other mastering information. They shall not be entered as LCCN information. Note on PART: The actual meaning of this string is not yet clear but the strings allow to further identify the medium, format, and other information. 1.
