Data Damage!

I came across this video while searching for "bad 80's movie" on youtube.
All I could find out about it are a couple of deleted wikipedia articles and this image.

Anyway check it out, it's really bad-

I found a harmonica. It was disgusting, but I asked the oracle how to clean them, and it showed me how to take them apart and clean them, so I did. It sounds pretty great except for one ill gotten key. Also the little button on the side to shift to the secondary scale must have broken off some time ago, the sliding function still works though. And it is not a spring, but just a tiny headless nail that retracts the metal bar. It looks fairly old, but there's no way to date it that I can find. It's also a little dented and a little more charming that the wikipedia article would have you assume.
See you next time.
