“ATF’s Latin Antique No. 520 was Marder, Luse’s Latin Antique No. 120; other founders had it simply as Latin Antique; though BB&S originally called it Latin No. 5. It is a wide, medium-weight face with very small, rounded serifs, and lacks the curlicues of Latin Modern or Modern Antique.” – McGrew. Lightface Latin Antique is a lighter weight.
This style was known in Germany as Breite Etienne (1860). Versions under this name were carried by AG für Schriftgießerei u. M., Bauer, John, Schelter & Giesecke, and Schelter & Giesecke. Anglian by Genzsch & Heyse (in-house, 1879) is very similar, too. [Seemann]
