There's a fellow in Germany selling a bunch of new-old-stock unfinished pipes on the bay of e (happy to provide details if anyone's interested), including briars and clays. I've bought a few of his lots just for grins. One lot was a set of sandblasted billiards. I should have taken a "before" picture, but here's the "after" pic:

I didn't do a lot to it, just added some yellow dye to warm up the color a bit, then buffed it with carnuba. The white buildup is extra wax in the crevices which has since dissipated after smoking a couple bowls of tasty tobacco. The stem was a little rough but I shined it up with a little carnuba and buffing compound (white diamond I believe).
I've got some more from this lot to play with; I'll post pics as I progress. My current project is sanding one down to remove the sandblasting roughness. & I just ordered a lot of 10 dublins.
I'm not a real pipe expert, but I will say that this "cheapie" (I scored 5 for $15) smokes as well as any briar that I paid actual money for :)
PS those dark spots are on the briar - they may be fills, I'm not sure, or maybe just natural discoloration.
PPS that's my actual hand; I'm not wearing a glove.
