Optical media and vinyl record pressing plant, established 17 Aug 2017 in Warszawa, Poland (EU), after the acquisition of GM Records (3). Vinyl records were pressed by 2 Lened and 7 Hamilton American presses.

Vinyl identification:
The runout matrix scheme is *******-xy,

****** is a 6 digit number
"x" identifies the disc side (A, B,....) and
"y" is the ordinal number of the master cut (first A side cut = A1, second A side cut = A2, etc).

the six digit metal part number can be accompanied by either "WMF" or another text, in accordance with the client's request.
Note: Often the matrix also shows "MONOPR". This identifies the broker who ordered the pressing and should be credited as Manufactured By only.

CD identification:
The matrix number scheme is dd######mm, where
dd is the date of the glass mastering day (01 - 31),
###### is a 6 digit matrix number (where # can be 0 to 9),
mm identifies the glass mastering month (01 - 12).

Example: 0408731504 was glass mastered on 04 April (2018); 1908353809 on 19 September (2017).
Note: The year cannot be derived from the matrix number.

When trying to credit the correct name of this plant on 2017 releases, the dd and mm glass mastering date in the matrix number can help direct you - any date before 17/08 belongs on GM Records (3); any date after that day belongs on wmfono.

When entering wmfono matrix numbers into LCCN, the full dd######mm part of the string should be entered. An example of how to correctly credit wmfono can be found on Abysmal Grief - Blasphema Secta.
