Yes the proposal was called the OTOMATIC it was a 76 gun (automatic reload 80rds/min) with an independent radar on an OF-40 chassis (italian version of leo1 for middle east export). The system was part of a bigger system in wich 1 otomatic was the chief of a group of four sidam (a quad 25mm on m 113 chassis).
Only 1 prototype of the Otomatic was built while 225 sidam were produced they have only optical aiming system and now they are surplus so if u want to buy someone……
Another use of the 76/62 oto (manual reoload) was on the rooikat wheeled tank.
