In late August, 1966, the uncut Italian version of Texas addio was rated VM18 ‘‘per le numerosissime scene di violenza, di efferata crudeltà e di sadismo’’. Three weeks later the rating became VM14, with cuts. A second version with new cuts but same running time due to a couple of additions was released in July 1972.
In the versions I know at least three scenes are cut: hot-branding on shoulder, pistol-whipping and death of Pedro.
As for L’ultimo killer, three scenes were modified to obtain the original T rating (all ages admitted).
