Regarding the Roehl collection: when attending the AMICA Convention in
Denver four or five years ago, one of the stops to see collections was
at a home outside of Denver which had several of the Roehl instruments.
I recall one of them was a Violano Virtuoso.  They were housed in a
portion of a barn on the property that was turned into a nice large
room.  They were not functional at the time, having just been moved.
I do not recall the name of the new owner.  I would have to dig out my
literature from the convention to obtain his name.  Perhaps someone
could elaborate further on this.
