Thanks buroak. I finished my restoration of that 09 Thorn and it's very handsome and smokes very well. I'm a convert to KBB/Kaywoodie.
Yesterday, I found a 4-digit super grain with the patent registration number on the "drinkless" stinger, threaded stem, no "KBB" on the shank, but solid cloverleaf on the side of the stem. I'm thinking it's from the late 1930s. I carefully sanded it to preserve the stampings. While the grain isn't especially "super", it's a great looking pipe and probably looks better than it did new. I'll be interested to see how well it smokes. I think it's the "slim billiard" shape, 5129.
I always love how the briar feels after I've taken off all the original finish. carefully sanded with micromesh all the way to 12000, and buffed with brown Tripoli, white diamond, and carnauba wax. It's like butter in your hands. So much nicer than the lacquered finish. I've found that with a lot of these older pipes, which were originally stained dark, you effectively get a contrast stain if you use a lighter stain for refinishing. Rub with some oil and finish with carnauba and, voila, beautiful grain.
Finally, I like your name, buroak. We had a GIGANTIC bur oak in front of our 125-yr-old farmhouse, which we moved from a few years ago. From the scars on the trunk, I'd say it had survived multiple lightning strikes over the years. Such a grand tree! I would've been heartsick to see it fall. When we moved, I planted some of the acorns from it in our new yard.
