The National Faithful Service Medal was a Nazi Germany medal of honor that was founded on 30 January 1938, in three grades (25, 40 and 50 years), to reward civilians and military in the employ of the German public services for long and faithful service.
All officials, employees, and laborers at any level of the public service (local, regional or national) who complete 25, 40 or 50 years service were eligible. All three awards were of the same design, but with different colour variants, depending on the class.
The third class award was for 25 years of service was a silver cross, with a silver wreath and a black enamelled swastika in the center of the cross.
The second class award was for 40 years of service was a gold cross, with a gold wreath and a black enamelled swastika in the center of the cross.
The first class award, for 50 years service, featured a silver cross, with a gold wreath and black enamelled swastika to the centre.
The reverse of both classes was stamped with 'Für treue Dienste' (For faithful Services). The ribbon for the medal is cornflower blue.
