In 1941 the US Congress passed Public Law 274 that gave the POTUS temporary (until 6/30/1943) power to requisition materials for the war effort.

What is interesting is in the limitations.
As pointed out by the other poster in the other forum (and I agree), it's obvious that in 1941 the POTUS and Congress were well aware of and agreed that the Second Amendment to the US Constitution was, and is, a RIGHT of the INDIVIDUAL citizens of the United States of America.Nothing contained in this Act shall be construed-
(1) to authorize the requisitioning or require the registration of any firearms possessed by any individual for his personal
protection or sport (and the possession of which is not prohibited or the registration of which is not required by existing law),
(2) to impair or infringe in any manner the right of any individual to keep and bear arms, or
(3) to authorize the requisitioning of any machinery or equipment which is in actual use in connection with any operating
factory or business and which is necessary to the operation of such factory or business
Also, this affirmation was made without actually mentioning the Second Amendment but note the use of "infringe", "individual" and "keep and bear arms".
