Röpke's book paratext confirms unbroken descent from a 1937 first edition, but not that the 'spontaneous order' wording is unrevised since then

The title page and prefaces of the 1963 English translation of Wilhelm Röpke's Economics of the Free Society are explicit about the book's editorial history. The title page states: "First Published in Austria in 1937 / Die Lehre von der Wirtschaft / (Julius Springer, Vienna) / Translated from the 9th German Edition / Published in Switzerland in 1961 by Eugen-Rentsch Verlag." Röpke's own 1962 preface adds that the draft was composed in Turkish exile in 1936 and published in Vienna "shortly before the National Socialist takeover of Austria," and that the Gestapo later destroyed the Vienna publisher's remaining copies. Translator Patrick M. Boarman's preface states: "Since the book first appeared in Austria in 1937, nine Swiss [German] editions of it have been published... Through the years, the author has continually revised and updated his book; all of these revisions and additions have been incorporated into this English translation."

This confirms a real, continuous line from an actual 1937 first edition through nine German editions to the 1961 text translated here — supporting the dating half of Bladel's claim. But it also confirms active revision across those nine editions, so the presence of the "spontaneous order" / "commanded order" passage confirmed in claim-ropke-1963-translation-confirms-spontaneous-order-commanded-order-phrase-primary-read does not, by itself, prove that exact wording was already in the 1937 original rather than added in a later German edition. The 1937 first edition itself has not been located or read by any vault session.
