Lost vintage shiny silver harmonica with intricate engravings in a brown leather case near a park in East Idaho.

I lost my beloved vintage harmonica while walking my dog in the park near East Idaho last weekend. It's a shiny silver color with some intricate engravings and came in a brown leather case. I've had it for years, and it holds a lot of sentimental value. If anyone finds it, I would greatly appreciate your help in getting it back!
