I went to buy my bass a few days ago and while I was there I saw THIS. It’s a 5 string upright/double bass or whatever you want to call it and it’s 5/4. Most basses are 3/4 and have 4 strings, it was huge. The people that played it before were 6’6”, but no one is playing it now so it’s just at the shop. It’s owned by an orchestra but they have no storage room for it so it was there. Sadly, it has a crack and the top is warped, but it’s still really cool to look at. There’s a cello next to it for a size comparison.
It’s at Hammond Ashley in Issaquah if anyone is interested. This isn’t for sale but there’s a ton of other string instruments.
