My Mauser book doesn't have but 2 paragraphs on the rifle... Supposed to be faithful copy of the standard-modell. They saw extensive use during the Korean war... Some were made by Mauser and others, the majority were made in Chinese arsenals.

China did also purchase K98icon rifles with the 12 point star on the side of the receiver but this was after the deliver of the standard-modell.

As for finding parts... I don't know, someone with more experience will hopefully come forward... I would assume any Mauser 98 type parts would work but I can't give you a definite answer either way.
