GUEST: It's my father's.

He, he bought it here in Saint Paul, Minnesota.

It's a hurdy-gurdy.

APPRAISER: Yep.

This is quite an amazing piece to find in a place such as Minnesota.

I think it's far from its home.

It's most definitely French work and it's actually signed by the maker.

And that looks like Bassot.

It's in great condition, actually.

I like to think of it as the first mechanical instrument to ever come along.

Um, it's, the origins of it are very old, and not really sure where it came from.

We don't really see it in Europe until, uh, come the 11th or 12th century.

It's a six-stringed instrument with strings that sort of pass through.

It's tuned at the top.

And if we slowly take this off, this is a wheel that is actually rosined.

The instrument is played by cranking that wheel.

And as it turns, the rosin on the wheel activates and aggravates the strings, and, and you get a sound just like a violin.

GUEST: Okay.

APPRAISER: But with a wheel... GUEST: Mm-hmm.

APPRAISER: ...it's continually playing.

GUEST: (chuckling) APPRAISER: Um, these here, these are called the tangents.

And this is the tangent box.

And you can see, it's a wood mechanism for actually playing the strings.

The earliest known, uh, forms of this in Europe, they were much bigger, and actually so big, that it would take you and I to play it, where I'd sit here and crank and you would play the tangent.

And it's not until into the, uh, 15th century where we see them in this form.

The inlay, I think it's actually whalebone and ivory, and that blac “whalebon” we know as, uh, here in the United States, as baleen.

Where did you find it again?

GUEST: It's something my, my dad brought home.

APPRAISER: Mm-hmm.

GUEST: It's just something he came across one day.

APPRAISER: (chuckling) GUEST: And, and he likes unique instruments.

APPRAISER: Mm-hmm.

GUEST: Musical instruments.

APPRAISER: And, uh, this is definitely£ (chuckles) APPRAISER: Okay.

GUEST: ...a, a, a good find, um... APPRAISER: I'll say, my dad from New Jersey never brought anything home like this.

(both laugh) GUEST: Okay.

APPRAISER: Um, do you know what he paid, uh... GUEST: It, it wasn't much.

APPRAISER: (laughing): It wasn't much, well, I think it's, uh, uh, quite a valuable piece.

Um, one in this condition, um, I would put at probably around between $4,000 and $6,000.

GUEST: Wow.

APPRAISER: It's a great thing.

GUEST: Wonderful.
