FN Fal Rifle...a nice, hard-hitting weapon in 7.62 NATO. I'm told that the best ones have receivers made by IMBEL, although any of the examples I've seen were more than adequate, regardless of manufacturer. Easily recognized by the swing-up carrying handle found on most versions.
This is the 1911-A1 Colt .45 which was standard issue to U. S. military troops 1920s thru 1970s until the Beretta M-9 became the standard issue. This differs from the 1911 which had the straight grip housing and minor parts that were improved upon in the 1911-A1.
