In 1936, Lewis Nolan Nomar patented this device, which is basically a large 40-round magazine for the 1911 pistol. He envisioned a military use for the device in trench raiding, giving men a compact weapon with a large capacity. Unfortunately for him, the device was both remarkably (and unnecessarily) heavy and obsolete the day it was patented. Not only was trench warfare a thing of the past, but submachine guns could and would do the job of his device better than it could. Ultimately, I believe only two of these were made and was never formally tested by the US military.
