The overlay of the Safety described looks typically Italian and resembles those found on many Italian Safeties of various brands (also Waterman and Montblanc). Osmia, strengthened from the 1930s onward by licence production of Parker models, was later taken over by Faber-Castell and withdrawn from the market in the late 1950s. In the early years Osmia did make high-quality writing instruments, e.g. the celluloid pens with cap top in cloisonné enamel, which counted among the European top class. Sarastro, by contrast, produced exclusively top goods. A clear attribution of the specific Safety would only be possible by inspecting the base model under the overlay.
