Pre WWI full ivory bagpipes

Pre WWI full ivory. Glasgow style, possibly Duncan MacRae or Lawrie. Exceptional condition. Pipes are oiled and undergoing a gentle polishing. I would estimate the age to be Circa 1920. Original ivory mouthpiece, but the tip is missing. The ivory bulb to the mouthpiece is cracked. One ivory mount on one tenor bottom is broken but fits together perfectly. There are no cracks in the wood. $4,000 USD
