Hello! I am trying to determine approx how old my grandfather’s harmonica I found whilst cleaning the other day. No Star of David as you can see from the photo but I’m not sure what else could help identify the age, any idea?
These models have been in production since 1923, but judging by label on the inside of the box, yours looks as if it could date from the 1970s or even 80s. But as these instruments don’t have serial numbers, it’s not possible to be more specific.
