DARKNESS ON THE EDGE OF TOWN US LP variations: Decoding two- or three-letter matrix hand etchings on the early pressings (Part 2 of 2)

NOTE: Vinyl discs reported here with the hand-etched matrix code "PPP" was found not to be pressed at the Pitman factory. Please check the updated information in the blog entry from 8/20/2022.

One yet unelucidated DARKNESS matrix code found
in some of the early U.S. pressings.

In some fraction of the early vinyl copies of the U.S. DARKNESS album released in June 1978, you can find at least four different varieties of hand-etched matrix codes, PN, PMI, PMN and PK. Each code specifies one of the four pressing plants that had been used unusually and temporarily for making Springsteen's fourth LP, due to the transient shutdown of the Pitman plant, one of the three major Columbia plants back then. In the last post, I attempted to crack these codes and proposed that: (1) the first and shared letter P might denote the Pitman plant because it is the most probable common term; (2) a second letter, N, M or K, refers to an initial of company that owned one of these pressing plants; and (3) a third letter, I or N, specifies the State where a company locates its own facilities. According to these assumptions, I interpreted the four matrix codes as follows: PN for Pitman/North American Music Industries, Scranton, Pennsylvania; PMI for Pitman/MCA Records, Pinckneyville, Illinois; PMN for Pitman/MCA Records, Gloversville, New York; and PK for Pitman/Keel Manufacturing Corp., Hauppauge (blog posts 1 and 2), New York.

As I first introduced here March in the last year, there is a small unusual variety of the early U.S. pressings of his fourth album, as to where they were pressed. These variants occurred because, when the LP was ready for production, the Pitman pressing plant, one of the three major plants used by Columbia Records back then, was not available for the operation due to continued labor issues that first happened on the 2nd of April 1978, according to Billboard Magazine. Thus far, I have confirmed that at least four vinyl manufacturing plants, excluding the other two major Columbia-related plants in Santa Maria and Terre Haute, made up for the shortfall in vinyl pressing at the early phase of the album release. The said four plants were owned by the following companies that had probably never been involved in Springsteen's album production before:
