Pre 1900 Henderson bagpipes
I'm going to start out with these pictures from a set that good friend Jim McGillivray had awhile back. I've only seen this cast silver on two other Henderson bagpipes, one dating back to Malcolm MacPherson and the other a presentation set with a shield dated 1916 but otherwise pre-date 1900. I'm including this here for your consideration. It's always difficult to afix a date to a set of bagpipes, however by adding up certain clues and remaining open-minded, we sometimes get lucky.
