***Rare early PLOMB wrench.
-
The Plomb Tool Company started using a stylized inverted triangle shaped like a "V" for the letter "O" in PLOMB starting in 1934, making it look like PLVMB. This design choice helped distinguish their branding during historical trademark friction with the Plumb axe company. So any PLOMB items with the "O" in the spelling would be dated 1934 or earlier. Evolution of the Logo
- 1934: The Plomb Tool Company introduced the inverted triangle design in Los Angeles to replace a standard round "O".
- 1945–1948: The prominent "pebble-style" finish era used the distinct PLVMB stamp widely on production hand tools.
