This text is solely dependent on the book titled "Expedient Homemade Firearms" by P.A. Luty. The content mentions that measurements are given in both metric and inch sizes. The main spring has not been completed due to it being excessively bent, which affects its connection to the trigger, sear, and magazine release. Additionally, there is a lack of mention about pins and screws within the context.
