That is a huge tomb stone, it must take several men to move them, isn't it?
And that is just a part of it. I suppose the original could have been 3 times bigger.
Phonograph was not rare in my country, but back then people did not take care of these items like we do today. Some of my items I don't use are going to be donated to a museum as I visited a telecommunication exhibition last year and those would fit in perfectly.
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.
