Swedish Match A.B., maker of Cricket lighters and White Owl cigars, agreed yesterday to buy the brands owned by the closely held National Tobacco Company for $165 million to add the Beech-Nut and Durango names to its Red Man chewing tobacco line. Swedish Match said it was buying the brands, formulas and inventory of National Tobacco, based in Louisville, Ky., which has annual chewing tobacco sales of about $50 million. Swedish Match is No. 1 in United States sales of chewing tobacco. National Tobacco brands will give the Stockholm-based Swedish Match about 55 percent of the United States chewing tobacco market and greater control over prices, which have been falling because of competition.
