?? I was told that as a matter of maintenance and precaution, we should change the timing chain and rails on our 1983 300TD and 1985 300CD every 100,000 miles. We change the oil on both cars religiously.

On OM60x engines timing chains tend to last about 400-800kmi if the oil is changed in a timely manner and you use good oil. Simple to check and measure the timing chain stretch! The short chain to the oil pump is virtually NEVER changed until the engine is rebuilt top down. A Mercedes diesel is not built OR serviced like 'Merican Iron.
