Codex Washingtonianus, also called Codex Freerianus, contains the four Gospels arranged in the Western order: Matthew, John, Luke, and Mark.
Notes on verification
Confirmed by Smithsonian's own museum page, Wikipedia, and an independent textual criticism wiki, all agreeing on the alternate name and the specific Western order of the Gospels. [cascade flags: wikipedia_dropped_other_sources_exist | tier=silver indep_score=0.875 clusters=2 claim_tier=notable]
