Ok, so your post made me pull out my harps…and there it was, a late '60’s Hohner Chrometta 8. Haven’t played it for years, but it’s a lot of fun if you learn. $88.00 new today, less on ebay, guess you’d have to boil it out, or better yet put it in a bourbon soak 
, my favorite, beer is to sticky. Saw this guy give it a whirl
Good luck.
