SUZUKI VIOLIN Mandolin 226 1967 Vintage with Case

This is a set of a SUZUKI VIOLIN Mandolin No. 226, manufactured in 1967, along with a hard case with keys.
As this is a product from quite an old era, the case shows signs of age such as scratches, dirt, and rust. However, the keys have been confirmed to be working properly.
The body has a few small scratches, but considering its age, I believe it is in relatively good condition.
I have confirmed that pressing the strings produces sound as usual, but I do not have much knowledge about mandolins, so please understand that this is a current item with unknown details.
The strings also appear to be original and have not been replaced for a long time.

I do not believe there is any major damage that would interfere with its use, but this is a used item inspected by an amateur.
There may be minor damages or other issues not visible in the photos.
Please refrain from purchasing if you do not understand or are sensitive about used items.

Thank you for looking.
