There were several great names among German clockmakers in the 19th and 20th centuries, including Gustav Becker, Junghans, Lorenz Furtwängler, and Winterhalder & Hofmeier, just to name a few. All these clocks are very desirable and collectible. Not much is known about Winterhalder & Hofmeier of Neustadt in Baden, but they made clocks for export, like the mechanism below, which was sold to the Colonial Clock Co. of Zeeland, Michigan, around 1920. The Winterhalder family began making clocks around 1730. The name Winterhalder & Hofmeier appeared around 1850. The company ceased production in 1933.
The following photos were taken during disassembly. The parts are large and heavy, when compared to other grandfather clocks. The design of the levers, particularly the chime lift lever, is quite similar to the design of the Herschede #1 mechanism with nine tubular bells. I believe the Herschede #1 design was based on the Winterhalder design.
