Update… after plenty of searches, (so curious about this… did I get a good deal? Is this a collectible?) I find out that P&C is a part of the history of Stanley Proto tools…
Combined from a few sources:
P&C is best known as a subsidiary of Plomb Tool (later Proto), but was an interesting and innovative company in its own right. Founded around 1920, the company had developed a very extensive line of automotive service tools by the end of the 1920s.
P&C was founded in 1920 by John N. Peterson and Charles F. Carlborg. Their first location was in Idaho, but the company soon moved to Oregon, first to Lebanon, Oregon and then to Milwaukie (a suburb of Portland). By 1924 the P & C Hand Forged Tool Company was listed in the Polk’s Portland City Directory, a business directory covering the Portland area. link
Further [Plomb Tool Company] expansion was done in early 1941 by acquiring P & C Hand Forged Tool Company in Milwaukie (sic) (Portland, Oregon). Mr. John Peterson & Mr. Charles Carlborg established P&C in 1920. The facilities augmented contract production and continued producing P&C tools until about 1964. link
Proto eventually ran into a legal battle over the company name, and ended up being eventually bought by Stanley’s Proto industrial tools division.
Now, I have seen no mention anywhere of woodworking tools… only automotive and such, and other than another plane I saw that had sold on ebay for $10, I couldn’t find any reference anywhere to P&C’s planes.
So the plane could be 60’s era, as Paul has suggested, or it could be earlier? Who knows… no newer than ‘64…
