This looks like an ex-piper clearing out.

Ran across some info on the “antler” set quite by accident today in the above.

David Latham, a piper from Libby, Montana, upgraded his original Matt Kiernan half set into a 3⁄4 set with a definite western flavor. They must fit in well with the venues where David’s band, Shaugh-nessy Hill, plays in Montana and Idaho. Probably lots of deer heads on the walls.The chanter and the tenor and baritone regulators were turned and bored in white maple by Bob Colley of Medi-cine Hat, Alberta, Canada. David stained them cherry to match the original set. He made the keys and springs out of brass and mounted them on the blocks. The regulator reeds are made of cane. The regulator caps and tuning pins were made from a matched set of Montana white- tailed deer antlers. The fittings on the drones are moose and white-tail deer antlers, and the bellows intake hole is mounted with an antler button from a Montana mule deer. The bag and bellows were also made by David.
