The first link says the exhibit features dulcimers made by Ernest Combs. I'm not familiar with this luthier. I could be wrong but from this bio he didn't seem very passionate about dulcimers

Still there is probably more to the exhibit and either way I am glad they are even doing a dulcimer exhibit.
I believe he made about 7 of them, no not a passion....
