I don't see what your question is. For your Vin number the W=Germany DB=Daimler Benz then the first 3 numbers are your chassis number 124. I don't know what the rest of the numbers are except that the last 5 numbers are usually the production number. You apparently already have the engine number, well at least the first 3 numbers. Usually it's something like 102.xxx. My '80 SD has the 617.950 diesel engine. My '83 TD has the 617.951 engine.
