STG 44 / MP43/44 rifles have been showing up all over the world in the last couple of years. An eagle-eyed reader spotted one at Ukraine’s newest and most popular tourist attraction, the private palace of their former President. The above image is a still from a VICE video (See 2:10. Embedded below) of the Presidents sprawling complex. Also take a look at his ammunition collection at 3:29.
Ukraine was invaded by Germany during WWII. Kiev was occupied from September 1941 until November 1943. It is possible this gun originated from the German occupation.
