This is a super rare example of an "NSKK" marked Walther KKW rifle. The NSKK was the National Maker Corp and it is very rare to find NSKK marked rifles and equipment. The receiver ring has the "Walther" banner marking and an Eagle over "N" proof. The rear top of the receiver is marked "KK-WEHRSPORTGEWHR." The barrel has the Eagle over "N:" proof on the left side behind "KAL. 22 LANG FUR BUCHSEN". The right side of the receiver is marked " WAFFENFABRIK WALTHER ZELLA-MEHLIS". The tangent rear sight is adjustable to 200 meters. The left side of the walnut stock is stamped with a large 1-1/2 x 1-1/2 inch German eagle holding a swastika with the "N.S.K.K." in a banner above that. Complete with a muzzle cover.

Very good plus with approximately 95% bright original blue overall, covered with light surface rust on the barrel, receiver, and barrel bands. The stock has been lightly sanded and remains in fine condition with a few light scattered dings. The NSKK proof is large and distinct. A very rare rifle that with a good cleaning and correct removal of the light rust would greatly improve this rifle. Mechanically fine.
