Greetings:

A collector friend is going to look at a barrel organ, hand-cranked,
ca. 1920, for possible purchase. He has scant literature on the subject
and wants to know typical values.  The information supplied is pretty
minimal, but if any of you can offer some general remarks on the
subject, or direct me to the appropriate printed (or on-line) material,
I'd appreciate it.

Thanks

Doug Rhodes
