Then, during a 1967 interview, Murphy mentioned the carbine’s serial number. Having memorized the number hints at the soldier’s connection with the firearm. At this point, serendipity raised its amazing head.
An employee at the Center of Military History Clearinghouse, intrigued, conducted a database search on the serial number and got a hit. Low and behold, Audie Murphy’s rifle lay resting among endless numbers of war memories.
Today, the “wounded carbine” complements the hero’s uniform, medals, and other memorabilia in the 3rd Army Division museum at Fort Stewart, Georgia.
Interesting article here, each enlisted personal had a serial number too. Never thought of it as serial number before, just like the other equipment.
