Bramah Core and Shear Line Ring

Core with shear line ring. The notches in the shear line ring allow the sliders to freely move up and down when the key is inserted or removed in the neutral position. Notches (at the bitting height) on the outer edge of each slider allow the core to rotate when correctly keyed. Image taken with a Nikon D-100 digital camera with a Nikkor 85mm 1:2.8D tilt/shift macro lens (with Kenko extension tube). Lit by electronic flash and various reflectors.
