I know this is Eva Antiqua SG Heavy, but looking to see if anyone is aware of any similar-looking free fonts. Thank you!

The Eva Antiqua SG is - as the name already tells - a Silver Graphics rip-off of Professor Rudolf Koch's Koch Altschrift designed for the Schriftgiesserei Gebr. Klingspor (1920-1922).
Many others copied the typeface too. Like Castcraft's OPTI Eve, David Rakowski's Spaden and Lilith, Arts&Letters' Salem, Fantazia Concepts Inc's FZ ROMAN 19, Brendel Informatik's Auvergne, Bitstream's Kuenstler165 BT and the Gabel.

Thanks for the suggestions! Very knowledgeable
