Thank you for viewing. I believe all three items are from around 50 years ago. I suspect they were made around the time folk songs became popular. Apparently, there were many harmonica manufacturers back then. I see Saka Horns elsewhere, but I couldn't find Apollon and Miyata Mini Harmonicas even when searching online, so I think they are rare. All are new and unused, but the Saka Horn's instruction manual and wax paper have deteriorated, so it seems they have been taken out and put back in a few times. For those who collect retro items and harmonicas, please consider purchasing them.
