Sony DADC closed the facility in early 2011 and migrated Pitman's compact disc manufacturing operations to the Columbia Records Pressing Plant, Terre Haute facility. At the time of the Pitman plant's closure, its average daily output had decreased to 16,000 CDs.
Pitman Vinyl Pressing Identifiers:
-PIT etched (See profile image)
-P hand-etched (and in a rather big size) instead of machine-stamped as up to 1981-82. (See image)
-P or p or CP - Stamped. Pitman, NJ (see image]
-On Capitol Records contract pressings, the number 54 in the runout and a large sized pressing ring on the labels.
Pitman CD Pressing Identifiers:
On CDs (1989 or later): "CMU P nn" (or "CMU P nnn") mould stamp in large font on inner plastic ring, readable from label side, or "P nn" (or "P nnn") in small font near the hole. (nn or nnn may be any number.) These codes should be added as Other Identifiers, but not Catalog Numbers, because they are not unique.
Note: After Sony's acquisition the plant was converted to CD manufacturing only, to make more CDs for CBS (now fully owned by Sony), but the discs looked very similar to WEA Mfg discs, except they had "CMU" in the plastic hub. This plant is known as Sony DADC SDM (Sony Disc Mfg). These different looking discs continued into the 90s, when Sony replaced the lines with the same ones DADC uses, so the discs were identical to DADC's other plants.
