I was searching for 6.5 Carcano brass online and found a listing for a brass with a NTW head stamp (photo). It is advertised as: "6.5x52 Carcano (Boxer) Primed Brass For Handloading by Prvi Partizan". I have searched the head stamp listings online and failed to find any mention of a brass case with a NTW head stamp. Does anyone recognize this head stamp?
