Gorgeous silver guilloché enamel box by Georg Adam Scheid (1837-1921), a prominent Viennese silversmith. Guilloché means "engine turning" and refers to a process of making patterns often seen in neoclassical architecture and bank notes. The machines used to produce guilloché patterns are no longer manufactured. Hallmarked GAS and 950. Sourced in London. Shows some scratching and small chip in enamel, but otherwise in excellent condition for its age.
