So, my avatar is the National Bohemian guy, Mr. Boh. The brewery in SE Baltimore has long since been converted to offices and luxury condos, but his giant neon face sits atop the building in a nod to the past (one that I see often from my roof deck). Pabst now owns the brand along with Colt 45 and other National brands and produces the beer God knows where. It could come out of the same vat as PBR, Old Style, and others as far as I can tell.
I really have few or no occasions where I drink macro swill, but I'll drink one if I'm eating crabs on a hot summer day. Pabst recently introduced Natty Boh on draft... even if they are all marketing, Pabst is smart with the brands.
Maybe now that the new management couldn't care less, they'll sell of the rights to some of their smaller brands and some enterprising Baltimore brewer will try to recreate the old recipe.
