Phonograph was not rare in my country, but back then people did not take care of these items like we do today.

things that is a commonly use by the people during a certain time most likely be use that way. same like smartphone or car, the vintage one will be cared so much for its history, but when it is abundant, some might use it to above its limit. ahhaha

so nice of you to donate some of your items, must be a good addition to the museum.
