A 1934 Mercedes-Benz 500 K Cabriolet A, chassis kommission number 16533, delivered new through the Zurich Mercedes-Benz agency to Curt Alexander Bally of Schönenwerd, Switzerland. Acquired in 1951 by Walter M. Halle, Cleveland department-store magnate, who had it restored and drove it regularly — finished in the firm's signature green — before donating it alongside his 300 SL to the Crawford Auto-Aviation Museum in 1971. After nearly two decades on public display, the car passed into private ownership in 1990 and received a full cosmetic restoration in the late 1990s.
