1918. Downright surreal.
I've heard of wood from old buildings being used for instruments as well; also wood from submerged timber. It's something I love about wood instruments...not only do they have a history of their own, but they also have the history of where the wood came from. Gives them a bit of a spirit, ya know? If that doesn't sound kooky.
My Dad plays violin, and his instrument is over a hundred years old. Neat to think where it may have been and what it's seen.
