If you see a 359 Waffenamt on a part that means it was produced and initially inspected at Walther. If you see a 37 inspection marking on a part also inspected by the 359 inspection team, that means that the part was initially produced and inspected at Walther before being sent to Sauer where it was used in the assembly of a rifle and given final inspection. It has been debated whether Walther actually produced any complete Kar.98k's. An example of a rifle possibly manufactured by Walther would be the blank receiver type with the 359 inspection marking on the receiver shown in BOTW. Our understanding of the German manufacturing of Kar.98k's as being rigidly setup around the 10 basic manufacturers is likely a gross over-simplification. The district-marked rifles, Luftamt marked late bSw's, Steyr camp rifles, and commercially-proofed rifles are other examples that do not fit into the simplistic Kar.98k by specific manufacturer philosophy.
