Vintage professional-grade plumb bob manufactured by the historic German toolmaker H. Boker (Henry Boker).

Production of this specific heavy trade variant dates between the 1920s and 1950s. Unlike common modern Boker pocket knives, original masonry and carpentry layout tools from this pre-to-mid-century era are exceptionally rare acquisitions on the Australian market.
