The earliest of BSR catalogs don't show any such pans, but the ones from the Red Mountain period show 4 different sizes, a tea, a 5-stick (5-S), a 7-stick (7-S), and a 7-stick large (7-L). By the mid-1960s, an Atlanta Stove Works catalog only shows the 7-S. Not sure if they made them after that, but don't recall seeing one marked in the later Century style.
