I've thought bacula were neat since I first learned about them. Still, antique is about the only way you'll get an oosik these days, given both the marine mammal laws, and the fact that walrus need Arctic ice to thrive, and that's getting in increasingly short supply.
Just think, if we can reverse global warming, there will be oosiks for all. After their first owners are done with them, of course.
Best,
