The case is marked with a large serial number along one side of the lower part of the case, and yes there is a cross reference to tell you what it is. You can measure the cylinders to see what size they are. There are so many manufacturers that I would not know where they might put their serial numbers.
Type 1 is like the engine that was in the Beetle and the ones that you see in KRs is usually the 1600 that I think was used in the Super Beetle. The type IV is the one that was used in the VW Bus. Anyone familiar with the engines could just look at it and tell you if it is a type 1 or 4. I have no idea what the 2 and 3 are. What is your objective?
