PN, PMI, PMN, PK, and PPP reported previously, and here PV — Having been interested in deciphering these dead-wax hand-etched codes associated with the U.S. early pressings of DARKNESS LP, I may finally be able to take a break for this subject by posting about the remaining last probable one. The above six dead-wax codes were uncommon for vinyl pressings made by Columbia Records since the code-specified pressing plants normally had not worked under the company's operation
"You don't see no music on the records unless you watch the grooves. And that ain't much. That's pretty boring,"
Bruce Springsteen once said. Despite his words, I have never felt bored when looking at these vinyl analog artifacts. 
I hope you enjoy reading this blog as much as I enjoy sharing information and my personal thoughts with you.

, except for PPP, which denotes Columbia's  Pitman, New Jersey pressing plant (see 11/19/2018 and 05/15/2021). The unusual pressing plants that joined in the album production, due to Pitman's labor issues, included those back then run or owned by North American Music Industries (NAMI) in Scranton, Pennsylvania (coded for by PN), Keel Manufacturing Corp. in Hauppauge, New York (PK), and MCA Records in Pinckneyville, Illinois (PMI), and Gloversville, New York  (PMN).

Collecting log: a plain white test pressing for TUNNEL OF LOVE U.K. limited edition picture-disc LP (Part 2 of 2)
It was January 2003 when I got what was advertised as a "test" pressing for the picture-disc edition of this album at $29.00 from an eBay seller in Bethpage, New York (disc's images shown previously in the following posts on  03/01/2015 and 01/01/2020). It came in a plain white sleeve but not in a clear plastic bag used for the regular picture disc. This pressing is indistinguishable from my copy of the commercial version in almost all aspects but the plain white appearance.
