Bulova 1927 Conqueror
scarce silvered dial, needs a crystal and correct crown, does show some case wear to back. I discovered when looking for movement symbol==(the triangle being faintly stamped)== the letters CAL(Charles A. Lindbergh) at the apex of the screw hole, very tiny, stamped. Extremely hard to photograph, but a photo is shown here. Has anyone ever seen/noticed this on their early Lone Eagle movement? Could this be a distinguishing identification for the earliest of the watches distributed?
