Your dual marked example should be 4/48. If I am correct, misterbill must have a 10” PL∇MB adjustable wrench dated 3/48 AND a dual marked 6” PL∇MB/PR∇T∇ adjustable also marked 3/48. That is kind of noteworthy that they were making both single and dual marked wrenches in the same month
Interesting that they are both from the same time with the different markings
These adjustable crescent type wrenches with 1948 date codes
forged-in when they were made by the J.P. Danielson plant in 1948 and
stamped with dual-marked branding at a time that may not have necessarily been the same time as they were made have come up before and I have stated my position on them before. Why would Plomb be
selling an adjustable crescent type wrench or any tool for that matter marked PLVMB and an adjustable crescent type wrench or any other tool marked PLVMB/PRVTV at the same time? And why would they be doing it in April 1948?
If anyone wants to re-visit my "Plomb Lawsuit Tools Production Timeline Revisited" thread, it is linked
here.
Here is an excerpt from the Lawsuit Tools Timeline I developed and posted there...
------------------------------------------------------------------------------------------------
- In March 1947 Plumb sued Plomb in an L.A. Federal district court and won; Plomb had a year (or until March 1948) to stop using its name as a trademark.
- On February 2, 1948, Plomb applied for a ‘PRVTV’ TM that said it was using the TM on paper, tags, decals, etc only.
- On July 13, 1948, Plomb was awarded the ‘PRVTV’ TM that it said it was using on paper, tags, decals, etc only.
- In October 1948, Plomb started running ads consistent with their on-paper-only TM application using ‘PRVTV TVVLS MFD. BY PLMVB’ as a theme.
- On November 16, 1948, Plumb sued Plomb again for contempt, and the court ordered Plomb to comply with the previous March 1947 order, and to pay Plumb any profits it made during the year after March 1948 (the date it was supposed to have complied by).
- In December 1948, Plomb closed down to re-tool for a solution to the November 16, 1948 contempt lawsuit that was called a "temporary expedient" and estimated to cost $130,000.
- On December 14, 1948, Plomb applied for a ‘PROTO’ TM that it now said it was using on packaging and tools.
- In early January 1949, Plomb re-opened.
- On January 13, 1949, Plomb lost an appeal against Plumb (171 F2d 945), and Plomb was given until March 1950 to fully comply with the previous March 1947 court order to cease and desist using “Plomb” as a trademark.
- Throughout 1949 Plomb embarks on a massive advertising and merchandising education and conversion blitz introducing ‘Proto Tools’. While they were making and selling the dual-branded tools, they were re-tooling across their plants to remove ‘Plomb’ completely by March 1950.

My explanation remains that the dual-marked wrenches could've been made at the J.P. Danielson plant in 1948, held over in stock while Plomb was struggling with solutions to the lawsuit issues, and stamped and sold with the PLVMB/PRTVT branding in 1949.
I have yet to see a PLVMB/PRVTV adjustable crescent type wrench or any other tool with forged-in markings and forged-in 1948 date codes.
Understand that I have no stake here other than logic. If I am wrong and these wrenches were made, dual-marked,
and sold by Plomb in 1948, it doesn't fit the timeline, and that would require an explanation. That's all I'm saying. That is my only interest.
