This is a 90-degree right-angle parallel mount dial pointer (part #122013-1). It features a 1 1/8" x 3/4" mounting base that transitions into a 90-degree curved section measuring 2 1/4" x 1/2", allowing the pointer shaft to ride parallel along recessed glass scales or internal dial tracks. This design was engineered to provide station tracking around cabinet bezels in 1930s through 1950s tabletop and console tube radios manufactured by companies such as Philco, Zenith, RCA Victor, General Electric, and Crosley.
