Couple of days ago I found an Italian 81mm mortar bomb marked according to Yugoslav marking standards. Bomb is designated as M48, but don't let it misguide you as Yugoslavia was using other model of mortar bombs marked as M48 or M48P1 which were Soviet 82mm O832D bombs repaired in Yugoslavia and fitted with UT M45P1 fuse which was duraluminum made of Soviet brass B-45-T. Some of the mines O832D used in Yugoslavia in late 40's...post WWII were fitted with Italian fuses IR81 and Soviet MP.
Markings on found are in cyrilic:
TREN. MINA M48
INSTANTANEOUS MINE M48
