3/4 John Center ca. 1900 bagpipe made of Cocus wood. Colin Kyo drone reeds. Note that at one point I shut the middle tenor off with my finger and then promptly reduced the pressure to let it come back in. I walk around.
As a personal comment, these drones are very bright but not brassy. Great drone reeds for a mere $68 (at the time of purchase). If I buy another set of drone reeds, it will be these for my Henderson pipes too!
