I have a slightly later but similar 30 hour New Haven with a Greek Parthenon scene and wonder if these clocks were made specifically for export. Mine was sold by Thomas B. Spike (Jeweler), who operated a shop from the late 1860s to at least 1892, Halifax Nova Scotia (Canada).
Fleet Time Co. assembled clocks in Montreal between 1936 and 1940 and sourced movements and cases from Germany. This is one of their mantel clocks. I have another with a Gufa Westminster chime movement but this is an unmarked time and strike with an unusual (to me anyway) external star wheel...
Movement serviced, case refreshed, dial has new tabs to keep it in place, new right side winding hole grommet. The moon hands are too short, still waiting for hands that are the correct length from a supplier.
