A New Old Stock (NOS) unsmoked Regal Dr. Grabow pipe is a vintage, factory-fresh American tobacco pipe from past decades that remains in pristine, never-smoked condition. Key CharacteristicsMaterial: Crafted from aged, high-quality Mediterranean briar wood with a tight grain.Finishing: Available in either a classic polished smooth finish or a textured rusticated finish. The Stem: Made of durable black vulcanite fitted with Dr. Grabow’s signature inlaid white spade logo on the side. Mechanical FeaturesAdjustomatic System: Uses a patented metal twist-lock screw and removable aluminum stinger mechanism (Patent No. 2461905) designed to cool the smoke and catch moisture. No Filters: Unlike modern system pipes that use paper filters, older Regal models rely purely on the metal stinger rather than disposable inserts. Factory MarkingsShank Stamps: Typically stamped with "IMPORTED BRIAR," "Ajustomatic," and the patent number PAT. 2461905. Factory Bowl Coating: Even though it is unsmoked by any owner, vintage Grabow pipes typically feature a dark mechanical "pre-smoked" carbon cake lining applied at the factory so the bowl was ready for immediate use.
