Sniper 7.92x57mm Anschuß ammo box '1944'

Here we have a very rare card ammunition box which once held 15 rounds of 7.92x57mm s.S. Anschußpatronen. 
 
These rounds were loaded to the highest standard of any German 7.92x57mm ammo produced during the war and developed, initially, to test rifle accuracy. However, it's unsurprising that some frontline Scharfschützen (snipers) were eventually issued with such rounds later in the war as proven by numerous Soldbuch records. 
 
By this stage, such rounds were only produced under the 'cg' headstamp code, as marked on the outer label of the 1944 dated box offered here.  
 
Very few of these Anschußpatronen boxes survive today, so this represents a wonderful opportunity for a collector of ordnance and/or sniper related items to secure a very nice condition example!
