This clock was made in 1885 by Friedrich Mauthe.
The symbol (bird over circle with intials F/M/S) indicates German Manufacturer Friedrich Mauthe, Swchwenningen Germany.
When I got it it needed a few adjustments and now runs great. I'm still making adjustments so it will keep good time. It is an eight day wind-up clock, not weight drivien.
The hanging wire is to advance the gong. It strikes once on the half hour and the time on the hour.
