Authentic WW2 German manufactured K98/G43 cleaning rod. This is not a repro! The threads on all the repros are incorrect and in fact may damage the threads on your rifle. Repros also do not have the "V cut" inside the notch to help keep the cleaning cloth in place, not to mention that the bluing also is too dark.

This mid to late war 1943-45 example has the typical rough manufacture marks and no serial number - by then the Germans had better things to do than stamp small parts. Standard 12 1/2 inch (32 cm) length will fit perfectly all Mauser 98k made during or after 1940 (please ensure correct length however by inserting a coat hanger type rod, should measure 12 1/2 to about where sight post is), as well as G/K43 rifles. 

Condition is fine, not bent, no rust or damage and original phosphated finish is 90% or better. At any rate it's guaranteed original.
