Hi -- I inherited a Triola recently.  Apparently my mom had researched
it a long time ago through the Smithsonian Institution here in
Washington, DC, and they sent her a copy of a page from a musical
encyclopedia which identifies it.

Is this a collectible?  How do you go about determining value?  It has
no case and only one roll on it.  Any help you can give would be
greatly appreciated.

Sincerely,
