The Montana Military Museum has received a rare weapon from the National Center for Unwanted Firearms. It took the museum more than 30 years to find the machine gun to complete the First Special Service Force story. Firearms included a 1940s Johnson Automatic Rifle, a Browning Automatic Rifle, a Japanese Type 26 Officer’s Revolver, and a rare 1941 Johnson Light Machine Gun.
