Description
The Commissioner of Internal Revenue, in 1873, prescribed this form of gauging rod for use with spirituous liquors subject to taxation. This ornate example is made of nickel-plated brass and marked “PRIME & MCKEAN / PATD MARCH 31 & JULY 12, 1870 / WASHINGTON, D.C.” and “U.S. STANDARD INT. REV.” and “Wine Gallons.” The whole is contained in a wood box. The form combines the ideas of Eli S. Prime (ca. 1840-1885), a gauger in Baltimore, and Edwin McKean (ca. 1835-1896), then of Nashville. The maker is unknown.
