Super Nice Richmond’s Improved Milk Scale RuleLactodens Meter Reading Rule with Boxwood SlideA super nice example of Richmond’s Improved Milk Scale Rule, a specialized dairy‑industry instrument designed for reading lactodens (milk density) values. These rules were essential tools for early creameries, dairy inspectors, and farm operations seeking to measure milk quality before the widespread adoption of laboratory glassware. Surviving examples with clean markings and a smooth‑moving slide are genuinely hard to find.
