The Iron and Steel Act 1949 transferred shares in approximately 90 iron and steel companies to the newly created Iron and Steel Corporation of Great Britain, taking effect from 15 February 1951. The Act was the most contested of Attlee's nationalisations and was substantially reversed by the Conservative-led Iron and Steel Act 1953, which began returning the industry to private ownership.
Per invariant 3, reforms are scored by what they did on each channel-separated axis, not by the party that enacted them. This fingerprint is how the policy-match engine finds historical analogues.
Explicit links are curated by the author. Inferred links are hypotheses in the library that test the same axes this policy moved — the framework's answer to "what does the data say about a policy like this?".
Ranked by axis-fingerprint overlap with this policy. Direction match bolded — those are the closest historical analogues. Shape of the match is what drives policy-outcome comparison, not the country or party label.
