Albatross wing bone extensions were quite common during the latter 19th and early 20th centuries, pretty much essential for "library" pipes. I doubt that the Butz Choquin in the video is sporting an actual albatross bone extension but more likely acrylic colored to mimic an albatross bone extension.
10 years ago, when I made an inquiry with the idea of replacing the albatross bone extension on one of my pipes because it had splits in it, I found the cost pretty damned expensive. The quote was $500 an inch for the real deal.
