If it says made in Italy on the side of the crankcase and no markings on the backplate,
AFAIK it's Italian made. If it's made in China, it would have 'China' cast into the bqckplate recess. The G series was manufactured in Italy and China, the S series was only manufactured in Italy. I've been keeping my eyes open for a barstock head from an S90 for awhile, I have an S90K which has the square cast head and I think it's ugly.
