The opening of the Wagner Brewing Company in 1934 brought hometown brewing back to the area for the first time in 15 years. The company was purchased by New Orleans based American Brewing Co. in 1939 and began producing the Regal Beer brand.
In 1958 the flailing brewery was purchased by Baltimore based National Brewing Company, after a bid by Anheuser-Busch was nixed by the Federal government due to antitrust regulations, and began producing their signature National Bohemian Beer, aka Natty Boh, alongside the Regal label as well as Colt 45.
The Regal Brewery closed in January of 1975 and, as far as I can tell, the brand ceased as well.
