#72 5X54 Bolivar Fuerte 554, ERDM Robusto Zavalla or Robusto (My experience is that the majority are ERDM overruns and the 72M is the most consistent of the line)

#84 Torpedo, Bellicoso, Figurado 6X54 ERDM Flor de Llaneza, Punch Gran Cru No. 2, Bolivar Fuerte Bellicoso, Flor de Allones Belicoso
The number 84 is rarely ever available. Some vendors refer to it as a 73 torpedo.
