Weber 34ICH

Hi, I've cleared out piles of stuff–give away or throw it. Had to crush cars as couldn't find buyers.
Found a weber 34ICH, an Italian made one so it's old. It's never been stripped or messed with.
But what engines/cars does it fit?
Likely jetting/serial numbers pls?
Ps weber were part of fiat. With the 'disagreements' production stopped for years. Later Spanish /American made ones not same build quality.
