RHYTHM's Small World This is an Organeet M729. It belonged to my grandfather, so I'm not sure how much it was used. The stickers are still new, there are no signs of use on the music box discs, and the parts that make the music box play don't seem to have deteriorated much, so I don't think it was used for long. This is just my personal opinion, so I would appreciate it if you could judge from the photos. I checked the operation, and I was able to confirm that only the music box works. The clock did not work. There is something like green rust on the battery terminals, which I think is the cause. Please understand that only the music box is in working order. Please also note that the outer box has some damage, such as stains. I will add photos in the comments section.
