This is a version of Gottlieb's 1971 'Dimension' made for export to Brazil then Italy. Our available Gottlieb Engineering Game Cards indicate this Model 306 add-a-ball game was in the Engineering Department on 10-27-70 marked for export to Brazil and by 1-12-71 had been released to the production line. Then, Model 306 reappeared in Engineering by 2-8-71 as an export to Italy and sometime between then and 4-16-71 (the date of our next available card) it had been released to Production. We do not know what differences exist, if any, between the machines exported to Brazil and the ones exported to Italy. 'Galaxie', its domestic version 'Dimension', and the replay version '2001', all made by Gottlieb in 1971, are the first pinball machines to feature multiple banks of drop targets.
