Hi noonsap,
Welcome to the Lugerforum.
There was a similarly marked "AFRIKA KORPS" luger discussed on this forum a couple of years ago... as I recall, after close examination of the photos, it was the general consensus of the membership that this particular gun had been marked in this manner by some owner hoping to raise it's collector value, or just to make conversation by installing an unknown marking...
No way to make a judgement call on your gun, (which I suppose might be the same gun since we don't know how or when you acquired it) without some good clear photographs of the gun and it's markings... so please post photos for the forum to examine... if you need help with this, just ask.
BTW, Lugers are known for their accuracy...
