I found this post on gunboards:
http://forums.gunboards.com/showthread.php?183023-SKs-outside-russia-in-1956-picGuy claimed the photo shows Russian SKSs being picked over after the Suez Crisis of '56. We're all about
not taking stuff off the net and regurgitating it here at SKS-Files, so I decided to take a look and see what I could find. It turns out that the photo is indeed from a book entitled:
The Suez Crisis 1956 written by Derek Varble.
I was able to figure out this is where the image came from:
The Suez Crisis 1956 - Page 87There are clearly some Russian SKS45's in the mix there up front, the magazine, bayo, and gas tube are unmistakeable. If this is the aftermath of the 1956 Suez crisis, it appears the Russians exported the SKS while they were still being manufactured. Pretty neat stuff and these guns are likely the genesis of the silly "Egyptian Contract" theories floating around out there...
