-Identifying CD's Pressed At: Allied Record Company- CD's pressed at Allied will have an "ARC" in the matrix. If there is both "ARC" and "SRC", then the CD was pressed at Allied but the glass master came from Specialty Records Corporation. CD's with an Allied Record Company logo means the glass master also came from Allied Record Company in the mid 90's before the plant was renamed WEA Mfg. Commerce around 1997.
-Identifying Records Pressed At: Allied Record Company- Records pressed here can be identified by the Allied topless lowercase 'ɑ' logo stamped in the runout groove area. A manufacturer matrix number usually follows the logo (B-00000 on LP/12" and R-00000 on 7", or K-00000 on 7" circa 1975). The processing of lacquer disc 'metalwork' / 'plating' was often subcontracted out to Sheffield Lab Matrix and is denoted by a "SLM △ 00000" / "SLM △ 00000-X" etching in the matrix/runout area (...sometimes appears without the SLM part).
Additionally identification can be made as follows;
1.) A lone "A" embossed in the label area like this would indicate it was pressed at Allied Record Company.
2.) An "E A S T" embossed around the center hole like this would indicate it was pressed at Specialty Records Corporation (sourced from metal parts that were originally made for use at Allied Record Company based on the etchings). NOTE that usually the "T" is the most visible, sometimes the only really visible letter.Specialty Records Corporation
