Here I'm following up on some of Jack Campin's suggestions:

Here's Wilkie's Blind Fiddler, 1806.

Here's an etching based on Wilkie's Blind Fiddler. Note that the position of the figures is significantly changed.

Wilkie's The Bag-Piper, 1813.

Richard Waitt's The Piper to the Laird of Grant, 1714.

I can't find a portrait of Neil Gow (or Niel Gow?) by Alexander Nasmyth, but he did a couple of Robert Burns.

Here's Linda McCann's web site which contains several small photos of her sculptures (which she calls "models"—why?). I see she has a calendar available.
