... and if it HAS been smoked, you might only need alcohol through the stem on a cleaner to get it up and running. or possibly a salt treatment of the bowl if what was in itconflicts with your tastes. not a significant amount of wear, and no damage, so no "restoration" needed, per se.
hope it becomes a great smoker for you. o)
EDIT: in fairness, the salt treatment: fill a briar's bowl with sea or kosher salt, making sure to place a cleaner through to the draft hole, then saturate the salt (carefully, don't f#@k the finish) with alcohol, and allow to rest until completely dry. this treatment is used to draw out old flavors and aromas out of the wood, or prefix sting cake, and is called de-ghosting. this may soften or subvert preexisting cake, so be prepared to ream before, after, or both. also, if it smells like LAT, and you mostly smoke big english blends (for example) it might not be necessary. or if your palate isn't to the point that a ghost would bother you. or (like me) if you don't give a toss and are willing to smoke a briar into submission. o)
