The 1938 Nazi gun law is very similar to the 1968 U.S. gun law.
Senator Thomas Dodd had the Library of Congress translate a German copy of the 1938 Nazi gun law, prior to passage of the 1968 U.S. gun law.
A copy of the letter from the Library of Congress to Senator Dodd is reproduced in "Gun Control" - Gateway to Tyranny, by Jay Simkin and Aaron Zelman.
