Makes sense to me, how else are you supposed to clear a room without replacing that butt stock with a folder. I mean, a guy has to upgrade to keep up with all the tacticool gadgets, right? This is just evidence that the tactical magazines are now making their way abroad creating demand in an ever expanding market.
It has long been held that a folding stock will allow for hip firing, for which bolt action rifles with 5 round internal magazines are ideally suited to.
My guess is that rifle has been around since WWII (wasn't part of Rommel's war in the desert of N Africa in what is now Lybia?). The rest of the stock looks pretty banged up, so looks like the folder or metal stock was a necessity.
