Steinway pianos are only made by the Steinway company in Astoria, New York and Hamburg, Germany. But Steinways are sold by Steinway dealers worldwide. Once a Steinway is sold by the Steinway company it may be resold as a used Steinway piano by the original owner and sold again after that, ad infinitum. In fact, many of the most sought after Steinways are from particular years or from a particular factory.
There are subtle differences between all Steinway models and collectors and musicians seek out these differences and will pay top dollar for a particular model such as a Steinway Model M or a Steinway Model B.
