I didn't polish the metal or oil the wood or anything. They came to me looking like that.
They cost $200.
But! They were missing the Bass bottom section, and the stocks.
I had Rick Pettigrew at Dunbar Bagpipes make a new Bass bottom section. He had some vintage catalin mounts to hand. The new section isn't a perfect match but it's very close.

I already had a set of vintage ABW stocks tied into a sheepskin bag so I just stuck these drones in that bag and began playing them right away. They haven't changed any that I can tell.
Several years ago I acquired a c1905 set of pipes which had been hung above somebody's fireplace for around 30 years. Luckily they didn't seem to have ever had a fire in the fireplace, because the pipes were in perfect condition, with no cracks in the wood or ivory.
I began playing them right away. I played them for several years, in the hot sun and in the rain and all the conditions that pipes are exposed to at Highland Games and funerals and such. They never developed a single crack.
What is so very strange is that when I sold them to another piper they developed a big crack in the Bass top section after he had been playing them for a couple months.
Also I ordered a set of Dunbar ABW pipes with "palm nut ivory" mounts. I played this set for a couple years and it was perfect. I sold it to another piper and within a month or two all the mounts had shrunk and became loose. I just can't explain it. I don't know what these guys are doing to their pipes! I don't take any special care of my pipes, just commonsense stuff like don't leave them sitting in the hot sun.
About setup I use a sheepskin bag, a Moose valve in the blowpipe stock, and no MCS or other "guts".
