German Vintage 4-tier Christmas Pyramid Carousel

This is an amazing piece that has been sitting in my parents garage forever! I finally asked if I could have it this weekend. I was doing some research on these and found them very interesting. These were started over 300 years ago in Erzgebirge Germany. I am not sure when this particular one was made but it seems to be very old. It is a bit dusty! It is going to take some time to clean this one up. I don't want to break anything.
