I didn't see the Panthers listed, but recently saw a TO&E listing the M47 tanks (1958), along with AMX-13s, and later, AMX-30s.
Companies of ten vehicles, e.g. 1 x Co. HQ, and 3 x 3 vehicle platoons.
Apparently, later, some companies had 13 vehicles, with 3 x 4 vehicle platoons. Not sure if/when all converted to that, but saw that mentioned for both the AMX-30, and AMX-30b models.
