Circa 1905-1910, based on the font style and 'Registration Applied For' stamp which indicates a new design at the time of manufacture.

Market value ranges from $150 - $350 USD depending on the clarity of the hallmarks and the functional integrity of the spirit vial.
Care & Maintenance
Hand polish with a soft cloth and Wright's Silver Cream; do not submerge in water to avoid moisture entering between the glass vial and the silver sleeve; store in a dry environment.
