All Steinway pianos were originally designed in NYC. Steinway designed the model O in ~1900, and by 1922, Steinway modified their design slightly to create the model L, however by that time, the Hamburg factory wasn’t incorporating the newer Steinway designs. The Steinway model L was made continuously in NYC until 2004 when compromises between the New York and Hamburg Steinway factories led to streamlining their production. From then on, both NYC and Hamburg produced the model O. History aside, Steinway experts and historians consider the two models L/O to be equivalent…but as far as the Steinway family goes, the model L was the improved version.
