This is a 45-degree offset parallel mount dial pointer. It features a 3/4" x 3/8" mounting base that transitions into a slight 45-degree curved offset measuring 1 1/2" x 1/2", allowing the pointer shaft to ride parallel along recessed glass scales or internal dial tracks. This design was engineered to provide clear station tracking around cabinet bezels in 1930s to 1950s tabletop and console tube radios manufactured by companies such as Philco, Zenith, RCA Victor, General Electric, and Crosley.
