Also known as Longwear Stamper Company, Long Wear Stamper Corp.

Please use "Mastered At" until additional drop-downs are created for the LCCN field (e.g. Metalwork).
When adding this profile to a submission, please compare and confirm that the etching conforms to the uploaded images. On some Warner Bros. and Capitol releases "LW" can be found in the matrix code but this is not an indicator for Longwear. See Capitol Records Pressing Plant, Los Angeles.

From lacquer discs this company made the metal parts that were pressed by Plastic Products, Presswell, Monarch Record Mfg. Co., Columbia Records Pressing Plant, Pitman, Specialty Records Corporation and others. Longwear's work is identifiable by matrix etchings of "LW" or "LWP". These etchings have not been found stamped, and the "L" can be either capital or cursive. Another key identifier is that the etching is generally placed well away from other matrix markings and is rotated 90 degrees in relation to other etchings.

Before at least 1984 Longwear was wholly owned by Mastercraft Record Plating, Inc.
The company president was Jack Berman around 1959.
