Angus, this page has a good summary about the G.55, rather accurate:
http://www.kotfsc.com/aviation/g55.htmAnd, Krusty, the Centauro was produced in numbers quite similar to the 205, only it was produced in North, after the armistice, that's probably why you mistook production figures.
I'd like to see the Sagittario, too, after the problem with tail was solved, she was an awesome fighter... but, having been produced in such few exemplars, I don't think it should be added to AH.
We do need Italian fighters and bombers for scenarios and AvA, I played a while in another sim that has such planeset and some good scenarios (Malta, Sicily) I assure you it can be a lot of fun. You will be surprised to see how an "obsolete" plane can nonetheless stand against better planes if properly flown, Krusty.
