Metal finished harmonica, standard size. High-quality sound! This is a memento of my mother, so I think it's an instrument she bought in the 1950s (^-^) The exterior is quite dirty and rusty, but it still produces a beautiful sound. - Brand: tombo? - Model name: soprano Harmonica? This is my guess based on the characters engraved on the body. Please understand that I may be mistaken. - Color: Silver, but it's quite old... - Material: Metal. The instrument part is made of wood. - Size: 13 x 3~2 x 4cm *These are the actual measurements I took, so please use them as a reference. I was going to throw it away, but since it's a musical instrument, I thought someone might want to use it even if it's old, so I decided to list it. It's a very old item... Or, perhaps someone who collects items from the Showa era... If there's anyone who understands and would like to purchase it (^O^), I would be happy. Thank you for looking.
