Polo Shuttle
A clock attributed by its seller to Sweden uses German movements and a central shuttle-slider rather than individual buttons. The maker remains unidentified.
Jerger-Parts Clock
Another late push-bar clock appears to use Jerger alarm-clock components inside a Swedish-style case and control system.
A Heavily Modified Survivor
One interwar-style clock combines foreign-marked movements, original alarm mechanisms, replacement parts, repairs, and later restorations. Its original form is difficult to reconstruct.
Historical Significance
These clocks are not peripheral curiosities. They show how equipment remained in service through repair, component substitution, and local adaptation—and why internal mechanics must be read as a history of use rather than as a simple maker label.
