First repair was June 18, 1911, second repair March 9, 1944 as written on key arms. Was nonworking when purchased in 2015 due to neglect causing soundboard to cracks and rodents to chew parts. Restored during my spare time trying to keep in original status between 2015- 2019 keeping all original parts, only had to fabricate/replace 9 parts! Just need the stops/pulls names to complete project. Sounds greats now, despite not knowing how to play. * these are suggested stop names and placement needs to be verified. Date based off style, and model 900 appearing in 1890 Chicago sales catalogs.
