^symbols^kept handy for^matrix-runout^submitting^:

Allied Record Company and/or Sheffield Mastering Lab
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" or just △ 00000 etching in the matrix/runout area (...sometimes appears without the SLM part).

NOTE: the Allied machine stamped logo in the runout etchings can be easily mistaken for a "Q" or a "Ω", but is actually the lower case 'ɑ'
