Cadogan Investments Limited is a subsidiary of A. Oppenheimer & Co. Limited. It was formed by Oppenheimer Pipe in 1920 as a holding company for its many recent acquisitions, including BBB, Loewe & Co., two pipe factories in St. Claude and others. It continued to acquire pipe brands and makers for decades, adding GBD and others to their marquee.
Both companies are currently located at 20 Vanguard Way, Shoeburyness, Essex, SS3 9RA. A storefront operates out of the same location selling pipes and smokers accessories under the name Cadogan Gifts, and also sells a wide variety of other items. Cadogan currently holds, among others, the trademarks for Dr. Plumb's, Irwin's, Comoy's, BBB, GBD, Loewe & Co., Medico, Orlik, and Ropp.
