Cog Winder, unusual hanging brass and wood clock.

Cog Winder, unusual hanging brass and wood clock. Wood back is like a schield with some brass ornaments, hollowed out in the back to accommodate the cog wind chain which hangs below the wood. Pull the chain that winds around two wheels. The clock resembles a ships clock on the wood. 12.5" high not including the chain or hanger. It has a permanent pendulum, brass case, black dial under glass, gold numerals, brass hands. The letters "SO" inside a schield, is the name or trademark on the dial. Possibly German or French. I cannot identify in the trademark books. Complete, good overall condition except the click isn't catching. Should be a simple fix.
