I research in collaboration with the museum Strausberg the local industrial history of our city. As you may know, Lochow & Zimmermann produced in Strausberg (15344, near Berlin). The company gave it only by 1900 and 1930. Unfortunately there is very little information about this company, a production index (year) on the piano number for age determination certainly not. Therefore, I try to gather as much information as worldwide only possible. 1907 the company was appointed purveyor to the Grand Duke of Weimar, changing your brand name in Hoflieferant. The "L / Z" trademark was registered 1921. If you'd be so nice, you can send photos of the piano and number ([email protected]
) for my collection. Where is the piano (country, city).
