Les, Jamie hasn't seen any, and believes there are none still in existence. As has been said above, he and a few others are attempting a reconstruction of them, based on information available - including tunes known to have been played on the pipes.

Jamie believes they died out mainly because the fiddle and other melody instruments had a better range for the tunes people wanted to play, so the pipes lost popularity.

This also seems to suggest they were similar to Highland pipes in their range, although different in other respects.
