Thank you Rod,
I found another relevant paragraph of information about Nordheimer pianos and a change in the production of these pianos that may have occured in 1927:
Theodore Heintzman's nephew, Gerhard Heintzman, was also a piano maker, and when Gerhart died in 1926, Heintzman & Co. continued to operate Gerhard company for several years. In later years they also produced pianos under the Gerhard Heintzman brand. In the 1920s (mikes note: 1927), when many Canadian piano manufacturers were struggling, Heintzman & Co. also took over the Nordheimer Piano Co, and in later years produced pianos under the Nordheimer name. Over the years, Heintzman produced pianos were sold under several brands names, and Heintzman also sold pianos produced for them by other piano manufacturers. Heintzman's top pianos were produced under the "Heintzman & Company" brand, with the "Gerhard Heintzman" brand being next, then the "Nordheimer" brand. Brands that were produced for them, and sold with a "From Heintzman & Company" decal were Gerhard, Weber, Stevenson.
And so, if this information is correct, I suppose one would conclude that after 1927, the Nordheimer piano was not the best piano that Heintzman made - its quality level was two steps below "Heintzman & Company" brand pianos.
Here's a summary of what I think can be concluded from the above quote from wikipeida:
"Nordheimer" name brand:
before 1927: of the highest quality
"Heintzman & Company" brand pianos: best quality pianos
"Gerhard Heintzman" brand pianos: second-best level of quality pianos
"Nordheimer" brand: the third-best level of quality.
Is my conclusion incorrect?
Do you find this to be the case Rod, that Nordheimer's built before 1927 are better quality than those built after 1927? Or do you find that all Nordheimer's where built to top-quality standards regardless of the year they were built?
Second related question: When considering Heintzman or Nordheimer pianos from the earlier part of the 20th century is 1927 an important date to be aware? (i.e. best to find one made before 1927) Or are all Heintzman and Nordheimer pianos, no matter what date they were made, generally considered to be of excellent quality?
